Design (verb) is the act of solution decision-making. Design (noun) is the product of doing so. The same can be said of “plan”. “Design” and “plan” differ only by application of the words to solutions oriented towards different types of elements, technology versus human.

    1. Systems Engineers, or Systems Engineering?

Abstract

Discussion frequently occurs concerning the question “what does a systems engineer do?” This paper looks at the nature of systems engineering and its relationship to the job title or role description “systems engineer”. This concept of a job title or role is contrasted with a view that systems engineering is (or should be) an integral part of the discipline of engineering. The latter view suggests that differentiation between systems engineers and other engineers is artificial. Is the use of the term “systems engineer” just a semantics issue, or does its use have a deeper significance? What are the options and their implications?

Introduction

The term “systems engineer” is widely used within a context of “systems engineering”. This usage contrasts with usage of the terms “systems engineer” and “system engineer” in the IT sector, often referring to somebody who implements or maintains IT systems. This paper will examine definitions of systems engineering, then expose sets of principles of systems engineering from two different sources. The applicability of each of these principles will be examined with respect to the engineering of systems of different complexities and technologies, and to what we will call “non-systems”, unitary objects. From the applicability analysis, the paper draws conclusions regarding the generality of the applicability of systems engineering practice within engineering practice. The paper concludes by discussing the positive and the potentially negative consequences of use of the terms “systems engineer” and “systems engineering” in some contexts, and recommends context of usage.

Systems Engineering

The International Council on Systems Engineering (INCOSE) is believed to be the largest professional society concerned solely with systems engineering. INCOSE defines systems engineering as:

“Systems Engineering is a transdisciplinary and integrative approach to enable the successful realization, use, and retirement of engineered systems, using systems principles and concepts, and scientific, technological, and management methods.” [1]

Significantly, the definition embraces only a statement of purpose (enablement – making possible), and is ambiguous as to whether the principles, concepts and methods used apply to the approach or to the realization, use and retirement. It is unclear whether, under this definition, systems engineering incorporates any practice of engineering at all. Unfortunately, this definition is not going to be useful for the purpose of this paper.

NASA has defined systems engineering as follows: “System engineering is a robust approach to the design, creation, and operation of systems. In simple terms, the approach consists of identification and quantification of system goals, creation of alternative system design concepts, performance of design trades, selection and implementation of the best design, verification that the design is properly built and integrated, and post-implementation assessment of how well the system meets (or met) the goals.”[2]

In the experience of the author, this NASA definition aligns well with the use of the term “systems engineering” in industry worldwide. The definition also strongly aligns with the focus of the 50+ INCOSE Working Groups on aspects of systems engineering, and with the ISO/IEC/IEEE standard 15288:2015 on systems engineering. [3]

The author’s preferred definition of systems engineering aligns closely with the NASA definition: “Systems engineering is an interdisciplinary, collaborative approach to the engineering of systems (of any type) that aims to capture stakeholder needs and objectives and to transform these into a holistic, life-cycle balanced system solution that both satisfies the minimum requirements, and optimizes overall project and system effectiveness according to the values of the stakeholders. Systems engineering incorporates both technical and management processes. Systems engineering excludes construction, except for construction within development.” [4]

Another attractive, more concise definition is “Systems engineering is the problem-independent and solution technology-independent principles and methods for the successful engineering of systems, based on systems thinking”. [5]

These last three definitions of systems engineering provide the basis for the subsequent content of this paper.

Systems Engineering Principles And Their Applicability

The hypothesis that systems engineering is applicable to the conduct of engineering in general, irrespective of the system being engineered, may be tested against each of a set of representative systems engineering principles. In this paper, two sets of principles are considered. The first is a set of principles developed by the author in 2002 and slightly refined over subsequent years. The second set was developed by the INCOSE Principles Action Team and published by INCOSE in 2019. [6]

For each principle in each set, the principle is rated by the author “Yes/No” for applicability to the engineering of:

  1. ST: a large socio-technical system, such as the country of Singapore.
  2. CO: a complex technology item such as an aircraft.
  3. SI: a simple technology item such as a pen.
  4. SO: software of any size and complexity.
  5. NS: a non-system such as a USA quarter coin, produced by forming a material into a shape and without plating.

3 Treat as goals desired characteristics that may not be feasible, but not at the expense of the requirements.

Note: “treat as goal” means that effort will be expended to achieve the goal which is related to the importance of the goal, and the probability of success. Where conflicts between goals exist, the goals will be traded off to maximize overall effectiveness.

Deductions From Applicability Of The Principles

If the mapping of applicability of systems engineering principles to various types and sizes of project is valid, one would have to conclude that systems engineering is not something different or special. Systems engineering is just about engineering things, any thing.

Intuitively, one would expect that the more novel, complex or critical a system were, the more valuable a systems engineering approach to its development would be. This intuition is substantiated by the conclusions of a 2012 joint study led by the Carnegie Mellon University (CMU) Software Engineering Institute (SEI) using data from 148 development projects. [7] The projects, ranging from small to very large, were divided into two nominally equal-sized sets, the less-challenging half and the more challenging half.

Correlation coefficients were developed between project performance, incorporating cost, schedule, and quality outcomes, and systems engineering practice. The correlation coefficients of +0.34 for the less challenging and +0.62 for more challenging projects indicate very significant benefit regardless of project challenge, but much greater benefit for the more-challenging projects. A more extensive summary of some results of the CMU study is provided in Figure 1.

For the study, the relationships between the variables were summarized using Goodman and Kruskal’s Gamma, a measure of association that expresses the strength of relationship between two ordinal variables. A description of Goodman and Kruskal’s Gamma appears in the book Elementary Applied Statistics by Linton Freeman. [8]

The study also provides a useful benchmark for the group of practices defined, for the purpose of the study, to constitute systems engineering practice. Significantly, these are not enabling practices according to the current INCOSE definition of systems engineering, but are mostly “doing” practices are aligned with both sets of systems engineering principles (my set and the INCOSE set).

Personally, I rarely use the term “systems engineer”, but I have lived and breathed systems engineering since 1985, the year when I realized how incompetent I was as an engineer. I was a good technologist in my field – radio engineering – but I didn’t have a clue as to how to go about applying that expertise in a way that consistently produced great results.

My view has solidified over the years that every engineer is, or should be, a systems engineer within the scope of their assigned engineering role(s). Systems engineering is not something separate from engineering in general; it is a way of practicing engineering in general. The variables are the scope of the task, the degree of systems engineering formality that is appropriate to that scope, and the balance of technical versus social skills needed. The scope of the task has variables of the specific technology or technologies involved, the diversity of technologies involved, the degree of integration of different technologies needed, and the degree of integration needed of specialty disciplines such as safety or cyber-security.

I am not alone in this view of systems engineering as an integral part of the discipline of engineering, that is, the principles and process component that supports the technology, math and physics component of the discipline of engineering. Many companies implement the ethos of every engineer being a systems engineer. That affects their hiring, their engineering procedures, their learning culture, their learning strategy, and their reward systems. And their performance!

My colleague Paul Davies added some further thoughts, observing from 40 years of experience that there are two essentially different approaches that organizations utilize concerning systems engineering:

Type 1 is a “stove-piped” industry, where the executive power is in the hands of single-discipline engineering empires. [9] Systems engineering is recognised as a necessary annoyance to glue the designs together, but the practitioners are subservient to whichever single-discipline expert happens to be in charge of the particular project. Career prospects of the “systems engineer” are limited. I can relate to Type 1 easily, having had many engineers but few managers from “Type 1” organizations participate in my systems engineering training courses, and having consulted to such organizations. Thankfully I have never been an employee of a Type 1 organization!

Type 2 is an organization whereby systems engineering is firmly embedded and the lead engineers on all projects are recognised as experts in both the technologies involved and in the process and integrative discipline of systems engineering. Indeed, single-discipline engineers are allocated to projects, to have their work directed by the cross-discipline “systems engineers”, and systems engineering is seen as a desirable career aspiration.

I share Paul’s views in the sense of Type 1 and Type 2 organizations being common. I add a Type 3 organization which is also common, where engineers work mainly in multidisciplinary teams, making the more important decisions collaboratively, creating a learning environment in which engineers may start as single-discipline and ignorant of systems engineering, and evolve to become multi-disciplinary and competent in systems engineering, usually while maintaining their original discipline strength. Some change discipline in the process, for example from electronics to software. The further along this evolutionary path an engineer travels, the more suited that person becomes to a role of leading a multi-disciplinary team. But engineers at any point on this journey can be, should be, and often are practicing systems engineering. Enterprises in sectors that develop complex systems in competitive markets or complex environments tend towards Type 3.

Some systems are engineered to comprise a diversity of technologies, for example a car. Other systems are engineered to comprise essentially a single technology, examples being a mechanical Swiss watch, a drug, a consulting company, Sydney Harbour Bridge, and MS Word.

The principles of systems engineering described in this paper can easily be checked-off as applying to all of these engineered systems; the benefits accrue accordingly. It is intuitive that the more complex a system is, the greater the risk due to that complexity, and the more valuable systems engineering practices become. Also intuitive is that, everything else being equal, the greater the diversity of technologies involved, the more complex a system solution is likely to be, and therefore, the more valuable systems engineering practices will be.

All of these aspects are thoroughly discussed in the 2012 CMU study. [7] That study also looked at the proportion of projects that implemented systems engineering as a separate group of “systems engineers”, versus systems engineering skills and responsibilities being distributed throughout the organization. The study concluded that the percentages were roughly equal, and the project performances were not different to a statistically significant degree. The study hypothesized that while centralized systems engineering is more effective at performing SE tasks, those efforts are less integrated with the work of the project and therefore have less impact on project performance.

The study would seem to suggest that my advocacy of “systems engineering to be practiced by all engineers” is neither supported nor negated by the data. However, there is more to the story that is not investigated in the study. My experience is that there is a big difference between having a policy of “systems engineering to be practiced by all engineers”, and having an engineering workforce in which that practice is occurring at a significant level of competence. The main challenge is the cost of educating the whole workforce. As a consequence, the education tends to be superficial, at least initially. Training a small group of SE leaders and having them try to influence the work of others requires less investment than training of a whole engineering workforce, notwithstanding the high return on investment observed from doing the latter.

With implementation of a sound systems engineering socialization strategy, involving among other strategies genuinely expert leadership, systems engineering champions, and systems engineering focus groups, the growth of systems engineering competence increases towards a “way of life” level at a rewarding pace.

When systems engineering becomes omnipresent in undergraduate engineering degree programs, the need for industry to train an engineering workforce in systems engineering will disappear. This can be considered a desirable end state. The education does not need to be called systems engineering, and arguably, there may be benefit in avoiding use of the term. I am encouraged to see many initiatives to integrate systems engineering into undergraduate engineering education, at an increasing rate. I am excited to be involved in some of these initiatives.

Systems Engineers, Systems Engineering And Professional Societies

A number of professional societies and industry organizations are active in advancing the discipline of systems engineering. Among these are IEEE, Institute of Industrial and Systems Engineers (IISE), International Council on Systems Engineering (INCOSE), Korean Council on Systems Engineering (KCOSE), National Defense Industrial Association (NDIA), Object Management Group (OMG), and SAE International. The membership of INCOSE, the leading society devoted entirely to systems engineering, is dwarfed in numbers by the memberships of IEEE and SAE, and yet, the constituency of INCOSE, engineers who would benefit from systems engineering, and their employers, is hugely greater than the IEEE and SAE memberships combined.

The INCOSE website has reflected a slow shift in orientation from systems engineers to systems engineering over the years. Whilst there is absolutely nothing wrong with the term “systems engineer” as a title for a specific job – it can be accurate and carries some justified prestige – the term when used as a synonym for someone who practices systems engineering – a race apart – disenfranchises the millions of engineers who could and should be practicing systems engineering. That cannot be good for attracting new members to systems engineering societies such as INCOSE – see https://www.incose.org/about-systems-engineering/careers-in-se or the INCOSE Systems Engineering Handbook (SEH) 4th Edition for examples. I believe that any orientation of professional society publicity towards systems engineers rather than systems engineering to be detrimental to attraction of new members. This is an issue for the Institute for Industrial and Systems Engineers, as well as INCOSE. On a positive note, I am encouraged to see that INCOSE is actively discouraging the use in education resources of the term “systems engineer”, by way of instructions to content contributors in drafting of the INCOSE SEH 5th edition, currently in development. The pointer is shifting.

Conclusions

A case has been made for the applicability of systems engineering to all possible subjects of engineering, based on a mapping of the applicability of two sets of principles of systems engineering to the development of:

  1. Socio-technical systems.
  2. Large, complex technology products and systems.
  3. Small, simple technology products and systems.
  4. Software-only systems.
  5. Non-systems – engineered unitary objects not meaningfully viewable as being constructed of interacting elements.

The case has been strengthened by study data that demonstrates the value of systems engineering for the engineering of small, simple systems as well as larger, more complex systems, the principal difference in application being the degree of benefit.

This demonstration of general applicability has led to a conclusion that systems engineering could be, and should be, practiced by all engineers regardless of job title, not only by “a race apart” small minority. A corollary is the need for systems engineering content in every undergraduate engineering degree worldwide, a pursuit that is gaining momentum.

The term “systems engineer” is widely used and is an accurate job title for many jobs. The term is appropriate for this use as a job title, often carrying justified prestige. However, the term is problematic when used in explaining and promoting systems engineering. The terms “systems engineering” and “systems engineering practitioners” are recommended for use in describing, promoting, explaining, advocating and communicating about systems engineering. In doing so, the present disenfranchisement of the millions of engineers without “systems engineer” in their job title who would benefit from the practice of systems engineering can be avoided. Based on the data presented in this paper, we conclude that society will benefit accordingly from better project outcomes.

Abstract

Despite the use of traditional systems engineering (SE) and project management (PM) models and tools, complex projects continue to experience cost overruns and delays. Major contributors to these failures include the lack of integration of multiple disciplines (especially program management and systems engineering) and their disparate models, tools, practices, and standards. Recent research has identified ‘Integration Factors’ and an ‘Integration Framework’ intended to facilitate the integration of program management and systems engineering for complex programs (Rebentisch et al, 2017).[1] However, a practical approach and model does not exist. This article examines an integration of models that provide a Management Flight Simulator (MFS) that can enhance and augment existing project management practices. It also provides an examination of the return on investment in bringing multiple disciplines together for knowledge gain, design flexibility, and product and project success.

Introduction

For most industries managing complex projects, cost overruns and schedule delays persist despite the application of recent project management practices and techniques. Numerous government projects including infrastructure, satellite programs, and weapon systems have experienced cost overruns and schedule delays costing billions of dollars of unplanned expenditures (Johnson 2018). For the Type 45 warship design, increased risks and costs were attributed to integration issues and challenges with 80 percent of equipment being new to service (Lombardi and Rudd 2013). For the Air Warfare Destroyer (AWD) warship design, the number one cause for cost overruns and schedule delays was advancing new technology (Parker 2016). Cost overruns and delays can be explained by technical challenges, over-optimism, and strategic misrepresentations. Remedies include improved information sharing and forecasting techniques, yet there is reluctance to invest in these approaches. In many cases, the return on investment may be unclear; in other cases, stakeholders may prefer to obscure the frequency and magnitude of cost overruns to evade accountability for project failures (Siemiatycki 2015). In a survey of 400 construction leaders, 62 percent of respondents stated that the biggest cause of project delays was due to the lack of collaboration and digital transformation (Finalcad 2020). With increased complexity and change, traditional management tools have failed to solve persistent problems (Sterman 2000, Walworth 2016). This can lead to late awareness or warning of problems and poor program performance.

The use of traditional project management tools and techniques is insufficient to achieve product and project success. The integration of well-known systems engineering models and business and product management lifecycle management curves that include the elusive techno-socio-economic and cultural factors in an organization can provide a novel and holistic perspective concerning product and project management. This integration of models can provide a Management Flight Simulator (MFS) that can enhance and augment existing management practices. In addition, use of the MFS and the gaming of change scenarios in response to risks can help bring disciplines together and build early knowledge.

There is a need for greater integration of program and project management application of systems engineering, and consideration of stakeholders across the value chain. In complex design projects, these stakeholders include engineers, management, the supply chain, planning and scheduling, and production.

Problems Faced in the Development of Complex Systems

Among the problems faced in the development of complex systems are varying discipline practices, unproductive tension between program leaders, and reluctance to adopt an integrated model that results in resorting to quick irrational decisions.

Varying Discipline Practices

Best practices and standards for the different disciplines include the Engineering Management Body of Knowledge (EMBoK), the International Council on Systems Engineering (INCOSE) Systems Engineering Handbook, the Systems Engineering Body of Knowledge (SEBoK), the Project Management Body of Knowledge (PMBoK), the Business Analyst Body of Knowledge (BABOK), and the Business Architecture Body of Knowledge (BIZBOK). However, these disparate roles, respective standards, and discipline-specific tools and models create confusion in terms of what to integrate. Moreover, these disciplines can often work in isolation, leading to inconsistencies in product information, tracking of design changes, and challenges in decision-making.

Unproductive Tension between Program Leaders

As noted previously, results from one study showed that there is unproductive tension between project managers of complex projects and chief systems engineers, that organizational performance was unclear, but that the use of integration tools could be beneficial in bringing disciplines together (Rebentisch 2017).

Reluctance to Adopt an Integrated Model that Results in Resorting to Quick Irrational Decisions

Concerns have been raised with respect to the lack of interest and buy-in from high technology organizations in embracing and adopting systems engineering models and tools. It was found that a low percentage of these organizations use model-based systems to capture data; whereas a high percentage still rely on document-based systems (Cameron 2018). Of note, only three percent of high technology organizations use model-based systems engineering tools to capture data and only 29 percent use a Model-Based Systems Engineering (MBSE) approach.

When problems occur in complex systems, the intuitive response is to find quick and easy solutions rather than long term effective solutions. This dilemma is apparent in the struggle between the systems engineer, project manager, engineering disciplines, and other stakeholders in the project (INCOSE 2015). Resorting to quick solutions may be caused by a stressful environment with time pressures or reluctance to apply cognitive effort. Whatever the reason, when recurring similar problems arise, shifting-the-burden from finding a fundamental optimal solution to quick symptomatic solutions can occur (Bellinger 2020).

As shown in Figure 1, adapting from a symptomatic quick solution to a fundamental optimal solution involves two balancing (B) loops and one reinforcing (R) loop (Bellinger 2020). The time delay or resistance in avoiding the fundamental solution leads to pursuing the quick solution. With this, side effects reinforce the problem including design issues. This forms a vicious reinforcing loop making it difficult to solve symptomatic problems. This reinforcing loop can create rework, cost overruns, and delays.

Figure 1. Shifting the Burden (Adapted: Bellinger 2020)

Use of an MFS Can Help!

The MFS can support pursuit of the fundamental optimal solution to symptomatic problems. It can do this through the automation of information, accessibility, transparency in results and ease of use. The MFS provides a common language of non-dimensional measures on a common platform of integrated SE and PM sub-models.

Inputs into the Fundamental Management Flight Simulator

From an extensive literature review, common integration requirement themes include communication and collaboration, social networking and recognizing team characteristics, early knowledge and a learning culture, early design analysis, mental models, understanding different perspectives, product quality and continuous improvement, and integration and simulation of information (INCOSE 2015, Senge 1990, Lee 1999, Laverghetta 1999, Rebentisch 2017). In developing the MFS, key aspects of the MFS include knowledge management, design change management, and the gaming of what-if change scenarios. Details concerning development of the MFS were presented in earlier work (Jonkers and Shahroudi 2020).

The MFS can help visualize and understand the causal relationships affecting decision-making. It can provide a clear understanding of system and program attributes and the impact of certain policies and decisions under various conditions. The MFS provides intelligence augmentation through a multi-experience dynamic user interface for what-if design change strategies. This can enhance and improve collaboration, learning, knowledge, and team effectiveness. Moreover, it can reduce project cost overruns and schedule delays.

Additional effort is required to develop tools and manage knowledge to enhance the design change process and to improve quality in production (Inayat, Dunbing and Leilei 2016). If knowledge can be quantified and an approach developed to advance knowledge in the design cycle, then design costs and schedule delays may be reduced. After an extensive review of knowledge management theory and research, it is not apparent that there exists a quantitative measure for measuring knowledge; the MFS is an attempt to develop this measure.

Knowledge Acquisition, Use, and Transfer

In a Project Management Institute (PMI) report, how knowledge is acquired, used, and shared was recognized as key to productivity, economic growth, and ultimately project and program success (Prusak 2015). It was noted that organizations that are most effective at knowledge transfer improve project outcomes by nearly 35 percent. It was also noted that when organizations create environments where employees can effectively transfer their knowledge to others, strategic initiatives will be completed more successfully.

Challenges in knowledge transfer can include finding out who has knowledge in the organization and how to create a learning culture for sharing knowledge. Use of the MFS and its integral social network analysis sub-model can help address these challenges.

It has been reported that 85 percent of technology and product costs are committed prior to detailed design, when little is known about the impact of design changes (Kennedy 2013). The lack of knowledge and design flexibility early in the design can postpone design change decisions when it becomes more expensive and difficult to implement these changes. Costs and time could be saved if it were possible to make quick, yet accurate assessments about the impact of change prior to implementing change (Morkos, Shankar and Summers 2012).

Design Flexibility and What-If Change Scenarios

According to the U.S. Government Accountability Office (GAO), half of defense acquisition programs experience cost overruns with the causes attributed to budget pressure, schedule pressure, and changing requirements (Cantwell 2013). Other factors leading to cost overruns and schedule delays include numerous design changes, technical errors and challenges in technology advancement and system integration (Ramanathan 2012). Design change management is viewed as a key process in developing the MFS. Set-based attribute and component changeability measures are used within the MFS for enhancing design change management.

One area for consideration in developing decision tools includes the effects of uncertainty in information and quantification methods for understanding the impact of change on different variables during the design (Chalfant 2015). The MFS provides for early knowledge and can predict the impact of changes and new technology on an existing system design, the organization and the project. The MFS uses set-based goal-based design and engineering principles in working toward a robust design. Set-based design has been reported as effective in improving design robustness and in reducing rework (Kennedy 2013). In set-based design, requirements and system design attributes are represented as ranges (instead of point values), where there can be explicit views of trade-off values prior to decision making. In point design, teams inefficiently move from one alternative to the next in search of a solution.

Understanding Underlying Product, Organization, and Project Interrelationships

Several studies reveal that only 16 percent of organizations are fully integrated and that over 60 percent of complex projects fail in terms of cost overruns and delays. It has been also stated that organizational and project dynamics have not been understood until it is too late (Rebentisch 2017).

It has been stated that several design models fail to represent the interaction across domains and don’t capture the aspects of time and the social sciences (Bartolomel 2012). The need for analytical decision management tools is supported by project and product failures in the past where it has been difficult to decide what to change in product design development when everything seems to have an influence (Behdinan 2011).

The field of systems dynamics (SD) can help in understanding the social and project dynamics within an organization. SD is used to analyze the behavior in organizational or social systems over time by describing and evaluating causal relationships. It can provide for a better understanding of complex systems and their behavior (Sterman 2000). SD loops can describe how knowledge generation and transfer can be impeded or enhanced. Likewise, SD loops can describe the impact of design changes on the program.

The Management Flight Simulator as a Practical Integrated Model

The MFS integrates systems engineering and management models through a digital thread for data-driven risk-informed decision-making. This MFS provides immediate feedback on whether a change is going to help or disrupt design integrity through the monitoring of system attribute trends and cues. It also provides the impact on lifecycle management curves using a SD sub-model.

From this feedback, several system, policy, and process levers are available within the MFS for what-if scenarios, with the goal to improve product, organizational, and project performance. The value in the emergent properties of the MFS as a decision support system is viewed as greater than from the sum of its sub-models.

The MFS predicts the state of the physical system and its impact on management curves where teams can respond to risks and disturbances with design change strategies using interactive controls. The management of attributes and management curves may be thought of as a control system, as shown in Figure 2.

When systems work well, there can be harmony and resiliency in their functioning (Meadows 2008). Resilience is the ability of the system to bounce back after a disturbance. In terms of the SD model, this property may be achieved through a rich structure of feedback loops that work in different ways to restore and stabilize system behavior (Meadows 2008).

This rich structure is achieved within the MFS with elements related to cross-functional processes, stocks, causal relationships through feedback loops, techno-socio-economic factors, and levers that can help to restore and stabilize system behavior. Integrated MFS sub-models include a Decision-Support System (DSS), Multi-Attribute Trade Exploration (MATE), Standards Risk Model (SRM), Design Structure Matrices (DSM), System Readiness Level (SRL), Social Network Analysis (SNA), Process Maturity Model, and the SD sub-model.

Impact of Lifecycle Management Curves

Like the butterfly effect, a small change in initial conditions or levers can have a cascading and significant effect on the management curves. Through the application of key system, policy, and process levers, the knowledge curve may be brought forward in design and the ease-of-change curve moved up, as shown in Figure 3 (Adapted: Blanchard 1998). It is proposed that this will postpone commitments; reduce the knowledge gap, cost overruns, and schedule delays; and better accommodate design changes, technology insertion, and procurement options throughout the design cycle.

The SD sub-model is based on a continuous predictive system that consists of stocks, flows, and differential equations. The position of SD management curves is monitored where corrective action may be taken by adjustment to policy and process levers.

Return on Investment Achieved by Using the Flight Management Simulator

The return on investment from applying systems engineering efforts has been investigated in other research where 14.4 percent of program costs invested in systems engineering was assessed as optimal for project success (Honor 2013 and 2016). The effort expended in using the MFS and the gaming of design change scenarios is estimated at well below 14.4 percent.

Through the adjustment of key SD model policy and process levers, the return on investment may be realized in reduced design change costs and schedule delays, as well as in other benefits.

The MFS can be used as part of existing risk and change management practices, providing the advantage of economy of scale. The costs of unexpected overruns in large complex projects can easily be in the millions of dollars per year. From a purely economic perspective, this justifies the expense of remedial measures including implementation of practical integrated models such as the MFS.

Causal Loop Diagrams and Project Management

The influence of both project and engineering system information on design changes, work performance, design maturity, and risk management are addressed in development of causal loop diagrams (CLD’s). In SD model development, CLD’s consisting of influencing factors, flows and stocks are defined. Feedback loops can be either positive reinforcing (R) loops or negative balancing (B) loops. There can be many CLD’s developed as part of the MFS and its SD sub-models. Of interest is the work performance CLD as it affects both product and project performance.

In the work performance CLD depicted in Figure 4, tasks are executed in accordance with the balancing (B18) feedback loop. The error rate causes rework through the reinforcing (R8) feedback loop. As the tasks “to do” and the error discovery rate increase, a reinforcing loop (R10) is enabled. The increased planned tasks and pressure to work harder act to increase the error rate and tasks to do through the reinforcing (R9) feedback loop. As the tasks completed are increased, the balancing (B19) feedback loop acts to reduce pressure to work harder and the error rate, leading to fewer tasks to do. Similarly, as planned tasks are completed, the balancing (B20) feedback loop acts to reduce the planned tasks. The task completion rate is affected by factors such as knowledge use, organizational integration, and the system readiness level (SRL) where the higher the SRL; the higher the task completion rate.

Levers for Improved Product and Project Performance

As part of the MFS, policy levers include on-the-job training (OJT) effort, gaming intensity, learning effort, team colocation, applying engineering principles, paying for VFI, and relational contracting effort.

Process improvement levers include knowledge, change, risk, communication, integration, supply, and strategic management. For instance, with an improved knowledge management process and application of engineering principles for a robust design, knowledge can be gained early in design and system ease of change increased, leading to reduced design change costs and schedule delays. As shown in Figures 5 and 6, the improved position or optimal setting of the knowledge and ease of change management curves can result in decreased design change costs and increased schedule performance. This provides a different and holistic perspective on integrated design and project performance management.

Conclusions

For most industries managing complex projects, cost overruns and schedule delays persist despite the application of conventional project management practices and techniques. Cost overruns and delays can be explained by technical challenges, over-optimism, and strategic misrepresentations. Suggested remedies include improved information sharing and forecasting techniques; yet there is reluctance to invest in these approaches. In a survey of 400 construction leaders, 62 percent of respondents stated that the biggest cause of project delays was due to the lack of collaboration and digital transformation.

The use of conventional project management tools and techniques is insufficient to achieve product and project success. There is a need for greater integration of program and project management with systems engineering, and for consideration of stakeholders across the value chain.

Disparate roles, varying standards for different disciplines, and discipline-specific tools and models create confusion. Moreover, the disciplines often work in isolation, leading to inconsistencies in product information, tracking of design changes, and challenges in decision-making.

The MFS can help visualize and understand the causal relationships affecting decision-making.

Additional effort is required to develop tools and manage knowledge to enhance the design change process and to improve quality in production.

The effort expended in using the MFS and the gaming of design change scenarios is estimated at well below 14.4 percent.

The MFS can be used to augment traditional project management tools, bring disciplines together, and provide early knowledge gain for product and project success. Development of the MFS offers a structured holistic approach to model integration that may be adopted in developing a suite of generic system models that may be reused and customized for specific product design and project applications. Showcasing practical integrated SE/PM generic models can help avoid the confusion concerning which models should be used for integration.

Demonstrating the value of changing mindsets and in SE/PM integrated methods, models, and tools includes continued efforts to reach out to those in the PMI organization who are involved in complex projects. In particular, it involves demonstration of integrated models that are built on a common platform using a common language that provides simplicity, transparency, automation of tasks, and an enjoyable user experience (UX).

Summary

Regardless of the approach taken, opportunities and partnerships with industry, academia, INCOSE, PMI, and other institutions will continue to be important in applying a PM/SE framework as well as practical integrated models that can work for everyone involved in developing and managing complex products and projects. It is encouraging to note the efforts of the members of the INCOSE PM/SE Integration Working Group (IPMSEIWG) who have adopted a charter in support of integration of systems engineering and program management and have established and are undertaking several ‘Initiatives’ to work toward strengthening and improving integration (see the article in the November issue of the Project Performance International Systems Engineering Newsletter (PPI SyEN 95) concerning the current efforts of the members of this Working Group).

Abstract

Many organizations that develop and manage large and complex socio-technical systems over the life cycle are in the need of a shift in mindset towards a complexity-oriented worldview, accepting the uncertainties and limits to planning and controlling that comes with complexity. This paper proposes a view of such a shift in mindset as an iterative and incremental process of organizational learning enabled by enhanced communication about the system and its context. Improved communication is supported by a toolbox of mechanisms. The presented approach has been explored in a traditional administration agency within the public transportation sector. Preliminary results indicate promising shifts in mindset on individual levels, with key knowledge carriers and ambassadors emerging with the potential of a self-sustaining shift. However, the long-term effects on the overall organizational capability remain uncertain.

Introduction

Many organizations and their life cycle management approaches are built on a mechanical view of the world (Boulton et al., 2015), where the system and its context are assumed to work like a machine, where facts can be analyzed, the future predicted, plans made and executed, and outcomes measured and controlled. A mechanical worldview provides a sense of order, purpose, and control. The nature of complex systems in an ever-changing context, however, is quite different. What is needed is a transformation to a more systems-oriented complexity worldview (Boulton et al., 2015), where the world is regarded as essentially interconnected, and where patterns and dependencies are shaped by history and context. A complexity worldview emphasizes the limits to certainty, that all things are continuously changing, and unexpected futures may emerge.

The capability of an enterprise to develop and manage large and complex socio-technical systems over the life cycle is dependent on both formal and informal structures within the enterprise. The formal structure is defined by organizational model, life cycle process framework, governance, and management policies. Roles and responsibilities, the intended flow of information between organizational units, and alignment, coordination and prioritization of work with respect to enterprise goals and objectives are all important aspects in the need of a systems perspective (Blanchard and Blyler, 2016). Informal structures are reflected by de facto communication patterns and information flows, organizational culture, and mindset. The mindset is the view of the enterprise and its constituent members of the system they manage. Mindset comprises mental models and assumptions regarding how to understand the system and its context and how to control or influence it towards an intended state.

Often, capability deficits or organizational problems are addressed by changes to the organization, governance models, or process frameworks, i.e. changes in the formal structures of the enterprise. This typically takes time and is difficult: and challenging when needs and problems are obvious. Furthermore, organizational changes tend to be ineffective, not providing solutions to the problems (By, 2005). The dysfunctions of traditional management systems tend to keep many organizations trapped in a constant “fire-fighting mode”, always dealing with the most urgent matters, with little time, energy, or insight to take a step back, re-think, and to learn (Senge, 2006).

This paper focuses on the possible impact of incremental “informal changes”, communication-driven shifts in mindset, and organizational culture in an environment where formal organizational structures and process frameworks are rigid and not subject to short-term changes (see Figure 1). The well-known Conway’s law (Conway, 1968) states that “organizations which design systems are constrained to produce designs which are copies of the communication structures of these organizations”.

We have previously reported on a case study from a traditional administration and acquisition agency within the public transportation domain, a highly process-oriented and project-focused organization with fragmented systems and life cycle perspectives, where we explored different communication mechanisms aimed at shifting the mindset and improving systems thinking capabilities within the organization (Karlsson et al., 2020). We refer to that paper for a more in-depth description of the identification and characteristics of each mechanism. This paper expands on the findings from the case study, and presents a framework to define the transformation of organizational mindset as a process of organizational learning.

Mindset Shift as an Iterative Learning Process

Bloom (1956) defines a generic hierarchical model for the classification of learning objectives in increasing levels of complexity. The six levels are knowledge, comprehension, application, analysis, synthesis, and evaluation (see Table 1). Shifting the mindset within an organization from a predominantly mechanical, project-oriented one towards a more complexity-driven, systems-oriented situation can be viewed through the lens of such a learning process, at the individual as well as at the organizational level. The learning process can be viewed as an iterative one, where the different stages represent an incremental level of increasing insight.

The first stage is the recognition of facts, accepting the degree of complexity of the system, and what that means. The system continuously evolves and new facts may emerge over time. Based on facts and complexity acceptance, an increased level of understanding of the sources of complexity and behavioral patterns may be built up. New patterns may emerge and complexity may increase or decrease over time. An increased understanding enables the ability to employ the complexity insights into the design of or alterations in the system architecture or operational scenarios, analyze different alternatives, and aggregate information on higher system levels in continuous loops throughout the life cycle.

Table 1. Shift towards a systems-oriented mindset as a learning process in different levels.

Level Characteristics of a systems-oriented mindset Typical questions of improved learning
Knowledge Recognition of facts, theories, or generalizations.
  • “What is a complex system?”
  • “To what degree is the system complex?”
  • “What does the level of complexity say about the system’s behavior and our ability to influence it?”
Comprehension An increased level of understanding of the facts, achieved through organizing, interpreting, and describing characteristics.
  • “Why is the system complex?”
  • “What interactions and dependencies give rise to the observed system effects?”
  • “Is the system complexity increasing or decreasing, and why?”
Application Understanding the context of the structures and rules and how to use the acquired knowledge of the system in new contexts.
  • “Why is the legacy system designed as it is, under what assumptions and constraints?”
  • “Do the same principles apply today and in the current operational context, or do we have to revise and question guiding principles and axioms?”
Analysis Examining information and information needs regarding the system and setting suggested system modifications or developments in a systems perspective.
  • “What are valid and feasible design alternatives or scenarios?”
Synthesis The coming together of different paths of information and design alternatives, forming a new whole.
  • “How do deliverables, individually and as aggregates of change, contribute (or not) to overall system capabilities or objectives?”
Evaluation The continuous judgement and defending of chosen alternatives in the light of new information, new knowledge, or new circumstances.
  • “The chosen alternative may have been right at the time, but is it still, knowing what we know now?”

The iterative nature of this model resembles the idea of the hermeneutic circle model (Coakes and Sugden, 2000), which expresses the dialectic principle that one must view and understand the parts in relation to the whole, as well as view and understand the whole in relation to the parts. Individual parts contribute new information that builds knowledge, and this learning process shifts the mindset of the observer. The shifted mindset then becomes the new context, in which the individual parts are viewed and understood in new light, perpetuating the learning process. The iterative nature of the process is captured in Figure 2.

Communication Support to Mindset Transformation

How does one bring about such a learning process within an enterprise? According to Conway, communication structures are a key to organizational output. Information flows, i.e. with whom different organizational units communicate, is important, as well as information content, i.e. what we say about the system. Thus, we developed a toolbox of support mechanisms for enhanced communication about the system (Karlsson et al., 2020). The mindset shift can be seen as going from a problem space, characterized by a process-oriented and project-focused organization with fragmented system perspectives, to a solution space where system complexity is accepted, different integrated system perspectives are visualized, inherent legacy design principles are understood and applied, and the development path of the system is continuously evaluated according to the current circumstances (see Figure 3).

The toolbox allows for different initial knowledge levels among individuals, yet still being able to adapt and make use of the toolbox. Also, more advanced people may be challenged and help out in the development of the next company generation of these mechanisms, as well as being mentors and ambassadors for less advanced colleagues.

Summary and Conclusions

We present a framework to view the shift to systems thinking within an organization as an incremental and iterative learning process driven by changes in how the organization communicates about a system at hand and its characteristics. The incremental and iterative nature of the model emphasizes building and applying knowledge and understanding in a perpetual learning loop. Shifting mindsets and organizational culture may well take time, but once key knowledge carriers and ambassadors emerge, the potential of a self-sustaining shift can occur.

The learning process may occur at the management/executive level, the team level, as well as at the individual level. The presented framework may be of interest for project managers, developers, or team members identifying with the challenges described, who identified the need for a complexity-oriented worldview and seeking supporting ideas to shift the mindset of their organization. The insights presented may also be interesting for senior management looking for a path and examples to improve learning within their organization.

The case study resulted in creating desired pull effects. The need for a system’s perspective in the organization was articulated both by management, project managers, and team members. For further work, we aim at development of an organization self-assessment model, to gauge the maturity of systems thinking and suggest approaches for toolbox application.

Abstract

The Digital Engineering Information Exchange Working Group (DEIX WG) is a collaboration between the International Council on Systems Engineering (INCOSE), the National Defense Industry Association (NDIA) Modeling and Simulation (M&S) Subcommittee, and the Department of Defense, Office of the Under Secretary for Research and Engineering (DoD/OUSE (R&E)). The DEIX WG supports the strategic objective to accelerate the digital engineering transformation by evolving the characterization of the content and relationships involved in the exchange of digital artifacts between disciplines and stakeholders throughout the engineering lifecycle. The DEIX WG aspires to ensure that digital artifacts are transferable within industries with complex systems. To address the challenges of digital artifact exchange, the Digital Viewpoint Model (DVM) sub team has created a concept model to define key concepts of exchange.

Introduction

As more organizations and disciplines move toward a model-based engineering (MBE) approach, there is a growing need to share, cross-reference, integrate, reuse, and extend models to digitally represent a total system model. Industries and governments have a long history of using a document-based engineering exchange approach; they must now convert to model-based digital artifacts with their currently disjointed use of models. Industries have the added challenge of exchanging engineering information in a new digital environment, while addressing issues like tool interoperability, model language and standards, obsolescence, workforce development, and organization cultural change. The goal is to synthesize actionable knowledge from various sources of digital information and models.

DEIX WG DVM Background

The initial groundwork for the DVM sub team began in 2018. The NDIA Modeling and Simulation Committee sponsored a two-day Digital Artifacts Workshop where the focus was to define how digital models can interoperate to support data exchange between two parties, an acquirer and a provider. The participants divided into three teams to analyze the perspectives of an acquirer, provider, and the conceptual modeling of Digital artifacts for exchange. The outputs from the workshop were used to create the first draft of the DVM concept model during the 2019 INCOSE International Workshop (IW). The team gained consensus on the DVM concept model at the 2019 NDIA Systems and Mission Engineering Conference, and launched an open DVM challenge in July 2020 to seek proposed implementations and extensions of the DVM concept model.

DEIX DVM Concept Model

The DEIX DVM Concept Model captures high-level concepts needed to describe the definition and relationships for digital information exchange. It is divided into three categories of ontologies: product, process, and stakeholder. The three categories are related to each other and provide a common language for specifying the content of digital artifacts that is represented by a digital view for user consumption.

DEIX Challenge

The DEIX WG initiated the Digital Engineering Information Exchange Challenge (“the Challenge”) in July 2020, culminating in the “Challenge Results Out-brief” at the Virtual 2020 NDIA Systems and Mission Engineering Conference. The Challenge seeks user-specific extensions of the DVM concept model from participants. The Challenge is not a competition between participants, but an opportunity for individuals and organizations to help shape the future of Digital Engineering information exchange by proposing enhancements to current practice, based on use case scenarios that support real-world needs. The use case scenarios will provide context concerning why the information is exchanged, the authoritative source for exchanged information, and how the information inter-relates. The results of the DEIX Challenge will serve to identify where the gaps are in current practice, as well as a proposed path forward to provide mature tools, standards, infrastructure, and languages to address the identified gaps.

The DEIX challenge submissions build upon the DVM concept model and propose one or more digital views that could be used for providing and consuming digital information pulled from multiple digital artifacts. Examples of digital artifacts that could be synthesized from various sources include Systems Modeling Language (SysML) models for MBSE; MATLAB performance models; Mechanical and Electrical Computer-Aided Design (MCAD and ECAD) models; Finite Element Analysis (FEA) models; and many others. The content, form, and function of the proposed digital views are documented in a concept model provided by the Challenge participants as part of the submission.

DEIX Challenge Status and Path Forward

DEIX Challenge submissions were accepted through November 13, 2020. Submissions were presented by the participants at the DEIX WG Challenge Results out brief on November 20, 2020. The results will be analyzed to identify similarities and trends in the proposed digital views as well as gaps that have been identified. The DEIX WG will then develop a plan to address the identified needs by creating a catalog of Digital Views informed by the submissions, and refine the Digital Viewpoint Model (DVM) Concept Model to provide a common ontology for relating the concepts in them.

Summary and Conclusions

Despite advances in the digital era, there are significant inefficiencies when suppliers, acquirers, and internal team members exchange engineering information following a traditional document-based approach. The DEIX WG aspires to ensure that digital artifacts are transferable within industries with complex systems. The DVM model seeks to model the concepts of curating a set of digital artifacts for exchange in a digital engineering environment. The DEIX challenge seeks to refine the DVM concept for developing constructs for assembling digital artifacts, and identify standard gaps necessary for exchange.

    1. The Impact of Human Factors Engineering, Systems Engineering, and Information/Communications Technology in Healthcare

By

George Grant, CSEP

Abstract

The United States (U.S.) healthcare delivery system lacks efficiency, quality, coordination, safety, is costly, and does not sufficiently support physicians, nurses, administration, patients, etc. (Fowler et al., 2011). For years, the focus has been towards the innovation of life sciences, physical sciences, and engineering of medical devices, instruments, and equipment treating patients (Reid et al., 2005). The advancements in healthcare have improved the quality of care, but also at a cost. Additionally, the lack of attention paid to the healthcare delivery system is one of the driving factors for increased costs (Reid et al., 2005). The purpose of this article is to discuss the impact of Human Factors Engineering (HFE), Systems Engineering (SE), and Information/Communications Technology (IT) associated with the healthcare delivery systems.

    1. What’s Different about an Integrated Approach?

Editor’s Note

As I began reading Integrating Program Management and Systems Engineering: Methods, Tools and Organizational Systems for Improving Performance shortly after its release in April 2017, it occurred to me that there must be a set of factors that differentiate a superior approach for development of complex systems from less successful approaches. Over the four weeks during which I digested “the book”, I evolved a list of factors, providing for each one a carefully articulated description of the factor and how it seems to present itself in each of the two approaches. This living document is in its eighth version. It identifies 32 factors with descriptions. I’ve shared the document with several colleagues over the past four years. As you have read in PPI SyEN, the “Integration Initiative” is gaining momentum.

I’m hopeful that this artifact will be useful to us as we continue to work toward the situation in which we are increasingly successful in developing, deploying, and maintaining complex systems.

Please let me know if you think of another factor or if you have suggestions concerning the current set!

You will see that there is unlimited opportunity to work toward continuous improvement on any program or project and in any organization, simply by identifying and describing the situation with respect to any factor and analyzing how it might be further strengthened and improved.

Let’s get better!

An approach that is used by several of the organizations for which I have worked (TRW, PRC, Litton-PRC, Northrop Grumman IT, and MITRE) is to have a small but effective process improvement group composed of several senior software and systems engineers. In the situation where this group is strongly supported by senior leaders, great things can happen. Once again, the critical factor is leadership.

    1. What’s Resilient Hospital Reference Model (RHRM) MBSE Project

Abstract

This presentation gives an update to an ongoing project by a volunteer cross-domain team (INCOSE, IEEE, FBI/InfraGard, and Medical Experts) to apply model-based analysis, engineering, and evaluation methods to develop a Resilient Hospital Reference Model (RHRM). Outcomes from this project include a model-based decision support capability that hospitals can use to enhance catastrophic event preparedness (protection, prevention, response, mitigation, recovery, evaluation, and reporting). The initial scope of the project emphasizes developing a resilience reference framework for hospitals to use in preparing for, handling, and learning from a prolonged power outage.

Speaker

Mike Pafford, a 22-year INCOSE member, and past Chesapeake Chapter President, is giving this project update presentation as a member of the volunteer Resilient Hospital Systems Engineering Team (RHSET) that has been working together on this RHRM MBSE project since 2017. Team members include MBSE practitioners from INCOSE, IEEE, and FBI/ InfraGard, as well as domain experts from across the national, regional, state, and local healthcare communities. The project was recognized with a 2018 Collaboration Award at the 2019 INCOSE International Workshop.

    1. System Requirements Engineering: A SysML Supported Requirements Engineering Method

By

Jean-Yves Bron

C:\Users\Ralph\Documents\SyEN 2020\December 2020\SE Pubs\System RE_A SysML Supported RE Method.jpg

The book deals with requirements engineering in the context of systems engineering. He proposes a method to guide this activity. The method is supported by the SysML modeling language. A first chapter aims to present the context and the associated definitions, to position requirements engineering in the processes system engineering, to define the modeling and its contributions, and to make the link with the management of IS projects. The second chapter is devoted to the proposed method for implementing the requirements engineering subprocesses. Each of eight activities is described before specifying how the SysML language can be leveraged to achieve it effectively. The third chapter is an application of the method to define the needs of the stakeholders of a system. The example is built on the basis of the RobAFIS’2018 competition. The fourth chapter continues the application of the method in the continuity of the IS processes to define the requirements of the same system. The appendices present a toolbox to realize the engineering of the requirements and also the complete results of engineering in Chapters 3 and 4.

Emily Lakdawalla

https://images-na.ssl-images-amazon.com/images/I/51mH-4fX7IL._SX348_BO1,204,203,200_.jpg

From the Amazon.com Website:

This book describes the most complex machine ever sent to another planet: Curiosity. It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work — its cameras, spectrometers, sample-cooking oven, and weather station — and describes the instruments’ abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out.

https://images-na.ssl-images-amazon.com/images/I/410MEGnUOCL._SX379_BO1,204,203,200_.jpg

From the Amazon.com Website:

Today, software engineers need to know not only how to program effectively but also how to develop proper engineering practices to make their code base sustainable and healthy. This book emphasizes this difference between programming and software engineering.

How can software engineers manage a living codebase that evolves and responds to changing requirements and demands over the length of its life? Based on their experience at Google, software engineers Titus Winters and Hyrum Wright, along with technical writer Tom Manshreck, present a candid and insightful look at how some of the world’s leading practitioners construct and maintain software. This book covers Google’s unique engineering culture, processes, and tools and how these aspects contribute to the effectiveness of an engineering organization.

You’ll explore three fundamental principles that software organizations should keep in mind when designing, architecting, writing, and maintaining code:

  • How time affects the sustainability of software and how to make your code resilient.
  • How scale affects the viability of software practices within an engineering organization.
  • What trade-offs a typical engineer needs to make when evaluating design and development decisions.

    1. PPI Requirements Specification Development Guide

A picture containing text, outdoor, sign, city

Description automatically generated

This guide, in its 4th Edition, is crammed full of good advice on writing requirements and the transformation of requirements information content into effective requirements specifications. A requirement is a required characteristic of something (anything). Requirements may apply to a capability system, a physical item, a software item, a database, an interface, or a service. Numerous studies worldwide have concluded that defective requirements are the single biggest cause of project problems – loss of capability, cost overruns and schedule slippages. These conclusions have been consistent across many sectors. Projects can be conducted without facing significant risk from requirements defects. The advice in this Guide will help.

    1. Journal or Systems and Software

Editors-in-Chief:

P. Avgeriou and D. Shepherd

C:\Users\Ralph\Documents\SyEN 2020\December 2020\SE Pubs\download.gif

The Journal of Systems and Software publishes papers covering all aspects of software engineering. All articles should provide evidence to support their claims, e.g. through empirical studies, simulation, formal proofs or other types of validation. Topics of interest include, but are not limited to:

  • Methods and tools for software requirements, design, architecture, verification and validation, testing, maintenance and evolution.
  • Agile, model-driven, service-oriented, open source and global software development.
  • Approaches for cloud/fog/edge computing and virtualized systems.
  • Human factors and management concerns of software development.
  • Artificial Intelligence, data analytics and big data applied in software engineering.
  • Metrics and evaluation of software development resources.
  • DevOps, continuous integration, build and test automation.
  • Business and economic aspects of software development processes.
  • Software Engineering education.

The journal welcomes reports of practical experience for all of these topics, as well as replication studies and studies with negative results. The journal appreciates the submission of systematic literature reviews, mapping studies, and meta-analyses. However, these should report interesting and important results, rather than merely providing statistics on publication year, venue, etc.

In addition to regular papers, JSS features two special tracks (In Practice, New Ideas and Trends Papers), as well as special issues.

In Practice is exclusively focused on work that increases knowledge transfer from industry to research. It accepts:

  1. Applied Research Reports where we invite submissions that report results (positive or negative) concerning the experience of applying/evaluating systems and software technologies (methods, techniques and tools) in real industrial settings. These comprise empirical studies conducted in industry (e.g., action research and case studies) or experience reports that may help understanding situations in which technologies really work and their impact. Submissions should include information on the industrial setting, provide motivation, explain the events leading to the outcomes, including the challenges faced, summarize the outcomes, and conclude with lessons learned, take-away messages, and practical advice based on the described experience. At least one contributing author must be from industry.
  2. Practitioner Insights where we invite experience reports showing what actually happens in practical settings, illustrating the challenges (and pain) that practitioners face, and presenting lessons learned. Problem descriptions with significant details on the context, underlying causes and symptoms, and technical and organizational impact are also welcome. Practitioner insights papers may also comprise invited opinionated views on the evolution of chosen topic areas in practice. Submissions in this category are limited to four pages and the first author must be from industry. Finally, submissions to this track should be within scope of the Journal’s topics of interest and they will be evaluated through industry-appropriate criteria for their merit in reporting useful industrial experience rather than in terms of academic novelty of research results.

New Ideas and Trends Papers

New ideas, especially those related to new research trends, emerge quickly. To accommodate timely dissemination of them, JSS introduces the New Ideas and Trends Paper (NITP). NITPs should focus on the systems/software engineering aspects of new emerging areas, including: the internet of things, big data, cloud computing, software ecosystems, cyber-physical systems, green/sustainable systems, continuous software engineering, crowdsourcing, and similar areas. We distinguish two types of NITPs:

  • A short paper that discusses a single contribution to a specific new trend or a new idea.
  • A long paper that provides a survey of a specific trend, as well as a (possibly speculative) outline of a solution.

NITPs are not required to be fully validated, but preliminary results that endorse the merit of the proposed ideas are welcomed.

We anticipate revisiting specific new trends periodically, for instance through reflection or progress reports.

New Ideas and Trend Papers warrant speedy publication.

Special Issues proposals

To submit a proposal for a special issue, please contact the Special Issues Editor Prof. W.K. Chan

Journal First Initiative

Authors of JSS accepted papers have the opportunity to present their work in those conferences that offer a Journal First track. Using this track, researchers may take the best from two worlds: ensuring high quality in the JSS publication (thorough, multi-phase review process of a long manuscript), while getting feedback from a community of experts and fostering possible collaborations during a scientific event.

Details may vary from conference to conference, but generally speaking, JSS papers to be presented in a Journal First track must report completely new research results or present novel contributions that significantly extend previous work. The ultimate decision to include a paper in the conference program is up to the conference chairs, not JSS. A JSS paper may be presented only once through a Journal First track.

Currently, the list of conferences with which JSS is collaborating, or has collaborated, through a Journal First track, is: ASE, ICSME, SANER, RE, ESEM, PROFES, and APSEC.

A complete toolkit for implementation of Earned Value Management

Performance-Based Earned Value uniquely shows project managers how to effectively integrate technical, schedule, and cost objectives by improving earned value management (EVM) practices. Providing innovative guidelines, methods, examples, and templates consistent with capability models and standards, this book approaches EVM from a practical level with understandable techniques that are applicable to the management of any project.

Clear and unambiguous instructions explain how to incorporate EVM with key systems engineering, software engineering, and project management processes such as establishing the technical or quality baseline, requirements management, using product metrics, and meeting success criteria for technical reviews. Detailed information is included on linking product requirements, project work products, the project plan, and the Performance Measurement Baseline (PMB), as well as correlating technical performance measures (TPM) with EVM. With straightforward instructions on how to use EVM on a simple project, such as building a house, and on complex projects, such as high-risk IT and engineering development projects, it is the only book that includes excerpts from the PMI®’s Project Management Body of Knowledge (PMBOK®), CMMI, the EVM System standard, systems engineering standards, federal acquisition regulations, and Department of Defense guides.

Performance-Based Earned Value allows both novices and experienced project managers, including project manager of suppliers and customers in the commercial and government sectors; software and systems engineering process improvement leaders; CMMI appraisers; PMI members; and IEEE Computer Society members to:

  • Incorporate product requirements and planned quality into the PMB
  • Conduct an Integrated Baseline Review
  • Analyze performance reports
  • Perform independent assessments and predictive analysis
  • Ensure that key TPMs are selected, monitored, and reported
  • Identify the right success criteria for technical reviews
  • Develop techniques for monitoring and controlling supplier performance
  • Integrate risk management with EVM
  • Comply with government acquisition policies and regulations

Written by Paul Solomon and Ralph Young, internationally recognized industry experts, Performance-Based Earned Value is constructed from guidance in standards and capability models for EVM, systems engineering, software engineering, and project management. It is the complete guide to EVM, invaluable in helping students prepare for the PMI®-PMP® exam with practical examples and templates to facilitate understanding, and in guiding project professionals in the private and public sectors to use EVM on complex projects.

Durward Sobek. MSU Photo by Kelly Gorham

A Montana State University professor has won national recognition for innovative education practices aimed at preparing engineering graduates to proactively solve problems and better society.

Durward Sobek, professor in the Department of Mechanical and Industrial Engineering in MSU’s Norm Asbjornson College of Engineering, was selected by the Kern Entrepreneurial Engineering Network as a 2020 Engineering Unleashed Fellow. The inaugural cohort for the award includes 43 engineering faculty nationwide.

“This is a really nice honor,” Sobek said. “I’m excited to continue exploring ways to bring innovation into the classroom to benefit our engineering students.”

Sobek restructured the class to focus more on open-ended, real-life case studies posed by a local manufacturing company. Students worked together in teams to conduct independent research and propose a range of potential solutions.

“It means the students need to ask a lot of questions and gather a lot of information about the context of the problem and who the stakeholders are,” Sobek said. “It’s a great indicator that these new approaches can be very impactful, both for students and faculty, as we work to prepare the future engineers and leaders that society needs”.

STANDARDS AND GUIDES

    1. Standards concerning the Aerospace Industry

The Aerospace Research Council provides standards in three categories:

The standards listed can be filtered by date.

    1. ISO/IEC/IEEE 24765:2017, Systems and Software Engineering Vocabulary

ISO/IEC/IEEE 24765:2017 provides a common vocabulary applicable to all systems and software engineering work. It was prepared to collect and standardize terminology. ISO/IEC/IEEE 24765:2017 is intended to serve as a useful reference for those in the information technology field, and to encourage the use of systems and software engineering standards prepared by ISO and liaison organizations IEEE Computer Society and Project Management Institute. ISO/IEC/IEEE 24765:2017 includes references to the active source standards for definitions so that systems and software engineering concepts and requirements can be further explored. 522 pages.

    1. Earned Value Management Systems Update

Provided by

Paul Solomon, PMP

The following email was sent to DOD and the Biden-Harris DOD Transition Team. It is also applicable to civilian agencies, FAR, and OMB. It is recommended that you and your organization consider these issues and begin initial planning to migrate from EIA-748 to government-wide standards, policies, and guidelines for Program/Project Management (P/PM) that are “in accordance with standards accredited by the American National Standards Institute (ANSI).’’

To both the current DOD Administration and the Biden-Harris DOD Transition Team:

There is a material and grossly misleading error in DFARS 252.234-7001 and related DFARS clauses. The erroneous DFARS clauses refer to a document that is obsolete: “American National Standards Institute/Electronic Industries Alliance Standard 748, Earned Value Management Systems (ANSI/EIA-748) (current version at time of solicitation).”

The ANSI/EIA-748 standard was terminated in Jan. 2015, per the NDIA IPMD Earned Value Management Systems EIA-748-D Intent Guide. Per the Change History Log, EIA Version C “Changed all instances of ANSI/EIA-748 to EIA-748 and updated the copyright for the EVMS Standard on the first page to SAE International.”

The change in ownership of the standard is important for four reasons:

  1. EIA-748 is not accredited by ANSI. Thus, its use will be nullified upon passage of the NDAA for FY2021. The House version, H. R. 6395, contains Section 1745-Requirements Relating to Program and Project Management (P/PM). It will revise the U.S. Code, Sec. 503(c)(1)(D), Standards for P/PM. The law, when passed, will require the Office of Management and Budget (OMB) to adopt government wide standards, policies, and guidelines for P/PM for executive agencies that are “in accordance with standards accredited by the American National Standards Institute (ANSI).’’
  2. The DOD EVM System Integration Guide correctly states:

EVM is one of the DoD’s and industry’s most powerful program management tools. Government and industry program managers utilize EVM to assess cost, schedule, and technical progress on programs to support joint situational awareness and informed decision-making. To be effective, EVM practices and competencies must integrate into the program manager’s acquisition decision-making process. The data provided by the EVM System (EVMS) must be timely, accurate, reliable, and auditable. Industry must implement the EVMS in a disciplined manner consistent with the 32 Guidelines contained in the Electronic Industries Alliance Standard-748 EVMS (EIA-748), not ANSI/EIA-748.

3. As asserted in my letter to OMB Directory Russell Vought, dated Oct. 27, 2021:

GAO reported that Project Management Institute (PMI) documents for project management and EVM are approved by ANSI. In contrast, EIA- 748:

• Was approved by the Society of Automotive Engineers (SAE), not ANSI.

• Think about the SAE grade of your motor oil. Capital acquisitions that cost over $100 M should be governed by a higher standard. Taxpayers deserve a higher standard.

4. As argued in my white paper, DOD Acquisition Reform: EVMS-lite to Program/Project Management, Rev. 17, EIA-748 is not a Voluntary Consensus Standard.

It is requested that:

  1. All pertinent DOD policies, instructions and guides, including DAU training and references, be amended to cite EIA-748 instead of ANSI/EIA-748.
  2. DFARS be corrected to refer to EIA-748.
  3. Planning be initiated to migrate DOD P/PM policy, instructions, guidance, and training, with regard to the use of EVM as a program management tool, from EIA-748 to the appropriate standards accredited by ANSI.

A DEFINITION TO CLOSE ON

  1. “The systems engineering method recognizes that each system is an integrated whole even though composed of diverse, specialized structures and sub-functions. It further recognizes that any system has a number of objectives and that the balance between them may differ widely from system to system. The methods seek to optimize the overall system functions, according to the weighted objectives and to achieve maximum compatibility of its parts.”

CONFERENCES AND MEETINGS

The featured conference for this month is:

The INCOSE International Workshop

29 – 31 January 2020 (Virtual Event)

INCOSE’s International Workshop is the event of the year for systems engineers to contribute to the state of the art. Unlike INCOSE’s annual International Symposium and other conferences, there are no paper, panel or tutorial presentations. Instead, attendees spend 3 days working alongside fellow systems engineers who are there to make a difference. Systems Engineers at all levels and from all backgrounds are encouraged to engage in working sessions, and contribute their knowledge and experience to take the discipline forward.

There are two kinds of working group sessions at the IW:

  • Working sessions, where the focus is on improving and completing working group products. Working sessions are ideal for contributing with and learning from the real experts in the field. Attendees planning to attend Working sessions are encouraged to contact the relevant session leaders before the event to facilitate planning.
  • Outreach sessions, where the focus is on disseminating the current state of the art to Workshop attendees with no or little previous exposure to the working groups. Attending an Outreach session is also the ideal opportunity to influence the future direction of a working group and perhaps the entry point for deeper working group involvement.

This will be INCOSE’s first virtual International Workshop following the success of the virtual International Symposium and subsequent virtual chapter meetings.
