Lean Enablers for Systems Engineering

Dr. Bohdan W. Oppenheim
Loyola Marymount University

A new product named Lean Enablers for Systems Engineering (LEfSE) is described. It is a collection of 194 practices and recommendations formulated as “dos” and “don’ts” of SE, and containing collective wisdom on how to prepare for, plan, execute, and practice SE and related enterprise management using Lean Thinking. The enablers are focused on mission assurance and the satisfaction of stakeholders achieved with minimum waste. The product has been developed by experts from the Lean Systems Engineering (LSE)1 Working Group (WG) of the International Council on Systems Engineering (INCOSE). LEfSE are organized into six well-known Lean Principles called Value, Value Stream, Flow, Pull, Perfection, and Respect for People. The LEfSE are not intended to become a mandatory practice. Instead, they should be used as a checklist of good practices.

Systems engineering is regarded as an established sound practice but not always delivered effectively. Sixty-two recent successful space launches indicate that mission assurance can be practiced well. At the same time, recent U.S. Government Accountability Office (GAO) and NASA studies of space systems [1, 2, 3, 4] document notorious major budget and schedule overruns, some exceeding 100 percent. Most programs are burdened with waste, poor coordination, unstable requirements, quality problems, and management frustrations. Recent studies by the MIT-based Lean Advancement Initiative (LAI) researchers [5, 6, 7, 8] have identified a mind-boggling amount of waste in government programs, reaching 70 percent of charged time. This waste represents a vast productivity reserve in programs and major opportunities to improve program efficiency.

The new field of LSE is the application of Lean Thinking to SE and to the related aspects of enterprise management. SE is focused on the flawless performance of complex technical systems. Lean Thinking is the holistic management paradigm credited for the extraordinary rise of Toyota to the most profitable and the largest auto company in the world [9]. Toyota is well known for practicing excellent Product Development and SE (what Toyota refers to as simultaneous engineering). For example, the Prius car design was completed in nine months from the end of styling, a performance level unmatched by any competitor [10]. Lean Thinking has been successfully applied in defense industry and in the U.S. military itself, (e.g., [5], and the Air Force Lean initiative named AFSO-21). It has become an established paradigm in manufacturing, aircraft depots, administration, supply chain management, health, and Product Development, including engineering.

LSE is the area of synergy of Lean and SE with the goal to deliver the best life-cycle value for technically complex systems with minimal waste. LSE does not mean less SE. It means more and better SE with higher responsibility, authority, and accountability (RAA), leading to better and waste-free workflow and mission assurance. Under the LSE philosophy, mission assurance is non-negotiable, and any task which is legitimately required for success must be included, but it should be well-planned and executed with minimal waste.

Fundamentals of Lean Thinking

Three concepts are fundamental to the understanding of Lean Thinking: value, waste, and the process of creating value without waste (also known as Lean Principles).

Value

The value proposition in engineering programs is often a multi-year complex and expensive acquisition process, involving thousands of stakeholders and resulting in hundreds or even thousands of requirements, which, notoriously, are rarely stable (even at the Request for Proposal phase). In Lean SE, Value is defined simply as mission assurance (the delivery of a flawless complex system, with flawless technical performance during the product or mission life cycle), satisfying the customer and all other stakeholders, which implies completion with minimal waste, minimal cost, and the shortest possible schedule.

Waste in Product Development

LAI classifies waste into seven categories: 1) Overproduction; 2) Transportation; 3) Waiting; 4) Over-processing; 5) Inventory; 6) Unnecessary movement; and 7) Defects. These wastes, in the SE context, are elaborated on in [11].

Lean Principles

Womack [9] captured the process of creating value without waste into six Lean Principles2. The Principles are abbreviated as Value, Value Stream, Flow, Pull, Perfection, and People, defined as follows:

1. The customer (either external or internal) defines value. The value proposition must be captured with crystal clarity early in the program.

2. Map the value stream. Prepare for and plan all end-to-end linked actions and processes necessary to realize value, streamlined, after eliminating waste.

3. Make value flow continuously. This should happen without stopping, rework, or backflow (legitimate optimized iterations are okay).

4. Let (internal or external) customers pull value. The customer’s pull/need defines all tasks and their timing.

5. Pursue perfection. Constantly improve, and make all imperfections visible to all, which is motivating to the continuous process of improvement.

6. Respect for people. Create a system of mutually respectful, trusting, honest, cooperating, and synergistic relationships of key stakeholders, motivating staff to exhibit top capabilities.

Lean Enablers for SE

LEfSE is a major product recently released in the field of Lean SE. It is a comprehensive checklist of 194 practices and recommendations formulated as the do's and don’ts of SE, containing tacit knowledge (collective wisdom) on how to prepare for, plan, execute, and practice SE and related enterprise management using Lean Thinking. Each enabler enhances the program value and reduces some waste.

As a set, the enablers are focused on providing more affordable solutions to increasingly complex challenges and improving response time from the identification of need to the release of the system.

The enablers deal with mission assurance and promote practices that optimize workflow and reduce waste.

The enablers are formulated as a Web-based addendum to the traditional SE manuals—such as “The International Council on Systems Engineering [INCOSE] Handbook,” ISO 15288, and similar NASA, DoD, or company manuals— and do not repeat the practices made therein, which are regarded as sound.

The LEfSE practices are organized into the previously mentioned six Lean Principles. The practices cover a large spectrum of SE and other relevant enterprise management practices, with a general focus to improve program value and stakeholder satisfaction, and reduce waste, delays, cost overruns, and frustrations3.

The full text of the LEfSE is too long for the present article, therefore only a brief summary is given herein. The full text is available online4.

  • Under the Value Principle, the enablers promote a robust process of establishing the value of the end-product or system to the customer with crystal clarity. The process should be customer-focused, involving the customer frequently and aligning the enterprise employees accordingly.
  • The enablers under the Value Stream Principle emphasize waste-preventing measures, solid preparation of the personnel and processes for subsequent efficient workflow and healthy relationships between stakeholders (customer, contractor, suppliers, and employees); detailed program planning; frontloading; and use of leading indicators and quality metrics.
  • The Flow Principle lists the enablers which promote the uninterrupted flow of robust quality work and first-time right; steady competence instead of hero behavior in crises; excellent communication and coordination; concurrency; frequent clarification of the requirements; and making program progress visible to all.
  • The enablers listed under the Pull Principle are a powerful guard against the waste of rework and overproduction. They promote pulling tasks and outputs based on need (and rejecting others as waste) and better coordination between the pairs of employees handling any transaction before their work begins (so that the result can be first-time right).
  • The Perfection Principle promotes excellence in the SE and enterprise processes; the use of the wealth of lessons learned from previous programs in the current program; the development of perfect collaboration policy across people and processes; and driving out waste through standardization and continuous improvement. A category of these enablers calls for a more important role of systems engineers, with RAA for the overall technical success of the program.
  • Finally, the Respect-for-People Principle contains enablers that promote the enterprise culture of trust, openness, respect, empowerment, cooperation, teamwork, synergy, good communication and coordination; and enable people for excellence.

LEfSE were developed by 14 experienced practitioners organized into two teams, some recognized leaders in Lean and System Engineering from industry, academia and governments (from the U.S., United Kingdom, and Israel), with cooperation from the 100-member strong international LSE WG of INCOSE [11].

Both SE and Lean represent challenging areas for research as they are grounded in industrial and government practice rather than laboratory work or theory. It is well-known that hard data about SE in large programs is difficult to obtain because:

  • The programs are classified and proprietary.
  • The companies are not willing to release such data even when it exists.
  • In many cases, the data is non-existent, of a poor quality, lacks normalization, suffers from discontinuities over long program schedules, and is convoluted with other enterprise activities.

As a result, it is difficult to collect the data needed to perform hypothesis testing. Therefore, rather than to rely on explicit program data, the enablers were developed from collective tacit knowledge, wisdom, and experience of the LSE WG members. Such an approach has been practiced for ages by numerous institutions, and is being described in [12]. LEfSE have been formulated for industry SE practitioners, but the development benefited from academic depth, breadth, and rigor; the latter emphasis provided by surveys and benchmarking to published data, as follows.

The development of LEfSE included five phases: Conceptual, Alpha, Beta, Prototype, and Version 1.0. It was evaluated by separate surveys in the Beta and Prototype phases and by comparisons with the recent programmatic recommendations by GAO and NASA [1, 2, 3, 4]. The surveys indicated that LEfSE are regarded as important for program success but are not widely used by industry. The comparisons indicated that LEfSE are consistent with the NASA and GAO recommendations, but are significantly more detailed and comprehensive.

Intended Use

The LEfSE are not intended to become a mandatory tool. Instead, they should be used as a checklist of good holistic practices. Some are intended for top enterprise managers, some for programs, and others for line employees. Some are more actionable than others, and some are easier to implement than others. Some enablers may require changes in company policies and culture. However, employee awareness of even those least actionable and most difficult to implement enablers should improve the thinking at work.

The creators believe that as many systems (and other) engineers, enterprise managers, and customer representatives as possible should be trained in the LEfSE, as it will lead to better programs. At this time, a large effort of offering tutorials and lectures about the LEfSE throughout INCOSE chapters, industry, and academia is ongoing.

The published product includes examples of the programs and companies that practice the given enablers. Also listed is the average value measuring the use of a given enabler in industry, obtained from the surveys.

A formal online process of continuous improvement and periodic new releases of the LEfSE has been set up as new knowledge and experience becomes available. A comprehensive description of the history of LSE, the development process of LEfSE, the full text of the enablers, the surveys, and industrial examples can be found in [11]. _

Notes

1. The early use of the term LSE is sometimes met with concern that this might be a “re-packaged faster, better, cheaper” initiative, leading to cuts in SE at a time when the profession is struggling to increase the level and quality of SE effort in programs. Our work clearly disproves this concern.

2. The original formulation had five principles; the sixth (the Respect-for-People Principle) was added at a later time.

3. LEfSE practices do not deal, however, with explicit financial steps such as cost estimating or earned value analysis, which are regarded as a separate activity.

U.S. DoD Releases Reliability, Availability, Maintainability, and Cost Rationale Report Manual

The Office of the United States Secretary of Defense and the Joint Staff collaborated on the Reliability, Availability, Maintainability-Cost (RAM-C) Report Manual to assist combat developers, project managers, and engineers to design RAM into systems early in a program. The manual supports life cycle implementation of the Sustainment metric, for which the Chairman of the Joint Chiefs of Staff (CJCS) issued new guidance in May 2007.

The Sustainment metric consists of an Availability Key Performance Parameter (KPP) and two supporting Key Systems Attributes (KSAs): Reliability and Ownership Cost. The CJCS guidance requires programs under development to create a balance between RAM performance in the field and the related costs of providing that performance - a distinct paradigm shift within the acquisition community that, once fully implemented, should result in improved value for major acquisition programs.

Survey of Architecture Frameworks

An Architecture Framework (AF) may be defined as conventions and common practices for description of architecture established within a domain or stakeholder community.

Examples of AFs include: Zachman, RM-ODP, DODAF, MODAF, GERAM, TOGAF.

Mr. Rich. Hilliard, a leader in this field, is collecting a list of current architecture frameworks in relation to his work with IEEE 1471, ISO/IEC 42010. An initial list is posted at: http://www.iso-architecture.org/ieee-1471/afs/frameworks-table.html

Mr. Hilliard would welcome any additions to this list. Additions may be submitted to Mr. Hilliard at: rh at wn.net

Pointed out by Francis Sota, the concept of view was described in BS (British Standard) 308 of the BSI (British Standards Institute) sometime after its formation in 1901. BS 308 governed the way in which artifacts could be represented on a 2-dimensional paper. The standard views are top view (e.g. floor layout plan), front view (i.e. front of a building), and side view (i.e. sideway of a building, usually with cross-section). To show an object in a 3-dimensional way on a 2-dimensional paper, one can use isometric view or perspective view. BS 308 standard was adopted by building architecture as well as engineering professions for the preparation of building design and construction drawings. So, a view, in essence, is a way in looking at an object from a chosen position within a coordinate system.

A viewpoint is an extended view based on a profession (e.g. mechanical engineer) or a trade (e.g. carpenter). Each stakeholder provides details of an extended view based on his/her professional/trade practices.

Isometric views are often used to show the construction or final assembly of a product (e.g. Ikea's assembly instructions of a closet from different pieces in a package).

Architecture description languages are basically equivalent to the rules articulated in BS 308 on how to create views and viewpoints. Francis Sota points out that engineering borrowed these terms and created different semantics. He points out that one thing is not quite clear in the ISO 42010 standard is that whether one view corresponds exactly to only one viewpoint or not.

Mr. Sota states that an architecture framework provides the rules for classifying views and viewpoints and the ways of creating architectural products for a specific purpose. For instance, DoDAF covers adequately the views of a set of military capabilities, but not the enterprise. TOGAF is suitable for describing an implementation architecture, but not an enterprise. In addition, a good architecture framework must provide semantics on inter-relating views and viewpoints of all architectural products to form a coherent set of architecture descriptions.


NASA Systems Engineering Framework

Have you ever wondered what NASA is doing to stay on the leading edge of systems engineering? Did you know that NASA has a Systems Engineering Excellence Initiative to stimulate and enable the development and advancement of a sound systems engineering capability across the Agency? As part of that initiative, the NASA Office of the Chief Engineer is taking a proactive approach to deploying the 3-axis NASA Systems Engineering Framework that was defined in the NASA Procedural Requirements for systems engineering - NPR 7123.1A NASA Systems Engineering Processes and Requirements. The NASA Systems Engineering Framework consists of three elements that make up the NASA systems engineering capability: 1) common technical processes, 2) tools and methods, and 3) workforce, knowledge and skills. The integrated implementation of these three elements is intended to improve the overall capability required for the efficient and effective engineering of NASA systems.

Since NASA management did not want the Systems Engineering Framework to become "shelfware," they committed the resources to ensure that it was actively deployed into the NASA systems engineering community, and that it actually impacted the way that systems engineering is implemented across the Agency.

Standards and Guides

ISO/IEC TR 24748-1 Guide to life cycle management

TR 24748-1, Guide to life cycle management, is in the process of publication by ISO/IEC (full report circulated: DIS approved for registration as FDIS).


ISO/IEC TR 24748-2 Application guide for ISO/IEC 15288
(System life cycle processes)

TR 24748-2, Application guide for ISO/IEC 15288, System life cycle processes, is at the Preliminary Draft Technical Report 24748-2 stage. The draft is presently being commented upon by ISO member bodies and Liaisons.

International Standards ISO/IEC 12207:1998 (Systems and software engineering—Software life cycle processes) and ISO/IEC 15288:2002 (Systems and software engineering—System life cycle processes) have application guides (ISO/IEC TR 15271:1998 and ISO/IEC 19760:2003, respectively) for the use of each standard individually. However, both International Standards were re-published in 2008 after significant revisions. As a consequence, the two published application guides no longer relate to the current versions of their respective.

ISO/IEC Technical Report 24748-1 (Systems and software engineering—Guide to life cycle management) is being published in 2008 to facilitate the joint usage of the process content of ISO/IEC 15288:2008 and ISO/IEC 12207:2008 by providing unified and consolidated guidance on life cycle management of systems and software.

ISO/IEC Technical Report, TR 24748-2 (Guide to the application of ISO/IEC 15288) supports use of ISO/IEC 15288:2008 and replaces TR 19760. This Technical Report and its companion, TR 24748-3 (Guide to the application of ISO/IEC 12207) - which replaces TR 15271 - continue and make use of the alignment effort inherent in the two revised International Standards.

The concept and structure of the TR 24748 series is also intended to allow more general application within engineering, regardless of specific technologies, according to ISO/IEC JTC1 SC7.


ISO/IEC TR 24748-3 Guide to the application of ISO/IEC 12207
(Software life cycle processes)

ISO/IEC TR 24748-3, Systems and software engineering -- Life cycle management -- Part 3: Guide to the application of ISO/IEC 12207 (Software life cycle processes) was in Working Draft stage as at 10 August 2009.

Some Definitions to Close On - Scenario, Use Case, Mission Profile

Scenario

A sequence of events especially when imagined; especially : an account or synopsis of a possible course of action or events (Merriam-Webster’s online dictionary)

Comment from Robert:
Operational scenarios play a major role in the successful engineering of systems. An operational scenario is a dynamic view of the system in operation, typically looking forward, with emphasis on the users' point of view. An operational scenario may be expressed in words and/or graphics as a sequence of actions performed outside of the system (including on the system), and by the system. A set of operational scenarios provides a reference for fitness for intended use.

The role of operational scenarios is well described in ANSI/AIAA G-043-1992, Guide for the Preparation of Operational Concept Descriptions.

Use Case

A use case is a description of a system’s behaviour as it responds to a request that originates from outside of that system. In other words, a use case describes "who" can do "what" with the system of interest. (Wikipedia)

Comment from Robert:
Use cases describe the interaction between a primary actor (the initiator of the interaction) and the system itself, represented as a sequence of simple steps. Actors are something or someone which exists outside the system of interest, and that take part in a sequence of activities in a dialogue with the system for some purpose. Actors may be human end users, human operators, or other systems. Use cases may define pre-conditions, triggers and post-conditions. Each use case aims to be a complete series of actions at appropriate level of detail, described from the point of view of the primary actor.

Thus, a Use Case is a form of expression of a scenario.

A “Mission Profile”

Is also a form of expression of a scenario. In practice, Mission Profiles tend to incorporate detail on timing and other key aspects of performance, together with the key external conditions under which actions are expected to take place. Thus a mission profile, in practice, tends to be more detailed than a use case. The concept of a ‘mission profile” is especially popular in the space and defence sectors.

A common issue in expressing scenarios, regardless of what they are called, is the expressiveness of the language used. Fully expressive languages provide for: sequence, potential concurrency, exclusive “or”, looping – exit loop under defined condition(s), iteration (defined number of iterations), and replication (defined number of potentially concurrent instances of the same action), together with inputs, outputs, commencement condition(s), completion condition(s), and measures and values of performance for each action (function).
