Reprise

In the first of a series of articles for this newsletter, I defined Cognitive Work, Cognitive Systems Engineering, Human Systems Integration and Human Factors Engineering. In the second, I outlined some important features of the practice of Cognitive Systems Engineering, discussed the distributed nature of cognitive systems, introduced my personal perspective on design and introduced two popular frameworks (Cognitive Task Analysis and Cognitive Work Analysis) for Cognitive Systems Engineering. In the third I outlined the framework of Cognitive Task Analysis. In this fourth article, I will outline the framework of Cognitive Work Analysis and contrast the two frameworks I have discussed. In the fifth and final article, I will illustrate how each of these two frameworks can complement existing Systems Engineering processes used in the design of large-scale socio-technical systems.

Cognitive Work Analysis

Cognitive Work Analysis is a multi-stage analytic framework for identifying the human-relevant work constraints in a socio-technical system (Vicente, 1999) in the form of:

  • The Hierarchical Structure of work in terms of the activity-independent constraints of the work domain at several levels of abstraction and decomposition (Work Domain Analysis)
  • The Partitioning and Organization of work in terms of Work Situations and Work Problems (Work Organization Analysis)
  • The Cognitive States typically established in the execution of work problems and the cognitive processes used to transition through states (Work Task Analysis)
  • The cognitive strategies, defined as the categories of cognitive processes, used to transform one cognitive state into another (Work Strategies Analysis)
  • The coordinative processes that support management and collaboration of work (Organizational Coordination Analysis)
  • Categories of human cognitive processing in terms of skill, rules and knowledge (Cognitive Processing Analysis)

The foundational assumption of Cognitive Work Analysis is that workers in a complex system operate within a large number of constraints. They remain free to act flexibly within those constraints and free, therefore, to act flexibly in response to unanticipated situations. The purpose of Cognitive Work Analysis is to identify and map out those constraints so that design efforts can take explicit account of them.

The products of Cognitive Work Analysis are theory-based Knowledge Representations (Figure 4) of the work domain, of individual and collaborative activities undertaken in the work domain, and of processes involved in the execution of those activities. These representations are developed from information gathered by use of cognitively oriented Knowledge Acquisition tools. The goal of Cognitive Work Analysis is to identify the basic sources of regularity or constraint, both contextual (technological, social, environmental) and human (intentional, perceptual, cognitive, active) that shape human action in a workspace.

Functional Interfaces, Functional Workspaces

Although Cognitive Work Analysis is not a method of design, its analytic products can be used to support any design method. Those who undertake Cognitive Work Analysis typically adhere to the principles of Ecological Interface Design (e.g., Dinadis & Vicente, 1999). An ecological interface is one in which information is structured in a manner that reflects the structure of the cognitive work (Tufte, 1997) so that it is readily assimilated and so that there are natural transitions between information elements. An ecological interface reveals to the operator the operation of underlying system processes, the interactions between system states, and the constraints on control actions.

A conventional interface displays the status of sensed system states as independent parameters. The operator then has the task of integrating those parameters into a meaningful interpretation of system function, a task that is cognitively demanding and that may be impossible under tight time constraints. While an ecological interface presents more information than a conventional one, it does not overload the operator because that information is integrated across levels of abstraction and the display supports a natural and compatible navigation that allows the operator to converge naturally on currently important constellations of information. Thus, an ecological interface reduces complexity of activity but it does not do that by reducing the complexity of the information but rather by managing it.

This strategy is commonly referred to as Ecological Interface Design because of its allegiance to the principles of Ecological Psychology. In my work, I have referred to this design process as Functional Interface Design (Lintern, Waite & Talleur, 1999) because the emphasis is on meaningful information that supports functional action versus data that must be interpreted. The most direct way of providing meaningful information is through display of affordances, where an affordance is defined as the ratio between what is required and what is possible (Lintern, 2000). For example, instead of showing fuel quantity, an affordance-based display will show the ratio between the distance that must be traveled and the distance that can be traveled given the remaining fuel. As might be obvious, if this ratio is not > 1.0, the required distance cannot be covered with the available fuel. The interpretation of such a display is direct and immediate.

In systems engineering however, we are less concerned with pieces of information than we are with constellations of information as they support cognition and action. Functional displays must be assembled into functional interfaces where the displays are not merely placed in a convenient arrangement but the information from the variety of sources is integrated to encourage seamless navigation to and foregrounding of that particular and specific constellation of information that bears on the current problem. As suggested above, the goal is not to reduce the complexity of the information space but to manage it in a manner that reduces the complexity of the activity or, at least, reduces the overhead work of finding and organizing within a complex set of information.

Additionally, if information is to be at all useful, it must lead to action. To that end, functional interfaces must be integrated with action support systems so that the interplay between analysis and execution is seamless. For example, a predictor display for aircraft control (Lintern, Roscoe, Koonce & Segal, 1990) will alert the pilot when action is required, will reveal the nature of the corrective action, and will show whether any action taken will return the aircraft to the desired flight path. This view of functionally integrated interfaces and controls leads naturally to the conceptualization of a functional workspace.

Cognitive Systems Design

Within the context of large-scale socio-technical systems, interface (or workspace) design constitutes only a part of the problem and in that broader context I prefer to speak of Cognitive Systems Design. We know well that individuals as cognitive systems perform at diverse levels of effectiveness. Furthermore, a committee of disparate individuals is also a cognitive system but many committees are not particularly effective; they often develop a mediocre product. Systems Engineers design distributed collaborative systems as in, for example, a net-centric command system. In the terms I describe here, a net-centric command system is a cognitive system. Whether by default or intent, we are designing cognitive systems and we should be designing effective ones. The framework of Cognitive Work Analysis identifies the full range of properties that need to be considered in the design of an effective cognitive system.

An effective cognitive system, whether it be an individual, a team or an organization, will make good decisions and plans and will execute courses of action in a timely and effective manner. That requires access to suitable information and to suitable action capabilities as would be provided by a well-configured functional workspace, but it also requires functional structures and coordinating capabilities that encourage effective cognition (and that discourage the opposite). Team and organizational cognition emerge via the coordinated collaboration of individuals and the effective use by participants of technological artifacts. Design of such systems requires cognitively oriented analyses of information processing and coordinative functions. At the very least, where the individuals are geographically distributed, the communications systems must support the types of interactions that are essential to functional coordination.

Frameworks for Cognitive Analysis; Task or Work?

Remarkably, interest in these two frameworks, Cognitive Task Analysis and Cognitive Work Analysis, emerged within the same time period. The work in the Cognitive Task Analysis commenced largely with the insights generated by Klein (1989). It has, however, become evident that these early insights were addressing only a part of the problem and so Cognitive Task Analysis has continued to evolve over the past 20 years from that powerful insight about recognition-primed decisions. It currently constitutes a more comprehensive suite of methods that can be used to address diverse cognitive functions. In contrast, Cognitive Work Analysis was first presented as a comprehensive system (Rasmussen, 1986) and although considerable work has been undertaken throughout these past 20 years on refining it and extending its application areas, its structure remains largely as it was first described.

At their inception, neither framework addressed design explicitly but considerable work has been undertaken through the past decade to address this neglect, resulting in the strategies of Decision Centered Design for Cognitive Task Analysis and Ecological Interface Design for Cognitive Work Analysis.

Those working with the framework of Cognitive Task Analysis have developed innovative methods of Knowledge Elicitation but their approach to Knowledge Representation has been opportunistic. Many of these representations have been developed with an eye to linking directly to the design problem. In contrast, those working in the framework of Cognitive Work Analysis have been opportunistic in their approach to Knowledge Elicitation but the approach to Knowledge Representation has been more principled and systematic, with many of the representations reflecting the structure of underlying theory although linking less directly to the design problem.

As might be imagined from my earlier comment that those with experience in the use of the critical decision method prefer to work with actual rather than hypothetical incidents, Cognitive Task Analysis has largely been directed towards improving existing systems. In contrast, the literature on Cognitive Work Analysis emphasizes the design of future systems. Nevertheless, there is no principled distinction between the two frameworks on this dimension; those working within the framework of Cognitive Task Analysis do sometimes apply their methods to the design of future systems by generalizing lessons construed from their analysis of current systems while Vicente (1999), in his treatment of Cognitive Work Analysis, allows that the study of current practice can inform an analysis oriented towards the design of future systems.

Finally, the framework of Cognitive Task Analysis is geared towards identifying points of leverage for design and towards designing cognitive support systems. In contrast, the framework of Cognitive Work Analysis takes a comprehensive systems perspective in emphasizing the design of functional interfaces and cognitive systems.

None of the characterizations I offer here should be taken as criticisms. Each of these frameworks has particular strengths and while Cognitive Systems Engineers tend to be somewhat parochial, there is considerable potential benefit in bringing these two frameworks together. However, the primary purpose of this series of articles is to illustrate how these frameworks can support acquisition of complex socio-technical systems and it is that issue I turn to in the next article.

Summary

In this article, the fourth in the series, I have outlined the framework of Cognitive Work Analysis and compared it to Cognitive Task Analysis. In the fifth and final article, I will illustrate how each of these two frameworks can complement existing Systems Engineering processes used in the design of large-scale socio-technical systems.

Handling the Complexity of Large, Technology-based Business Ventures

Erik W. Aslaksen
Sinclair Knight Merz
100 Christie Street, St. Leonards, NSW 2065, Australia

It is argued that the systems engineering methodology, now increasingly accepted as the preferred approach to complex projects also outside defense and aerospace, should be extended into the front end of commercial business ventures, in order to assure that the engineered solution fully meets the business objective.

Many business ventures involve the creation of large, technology-based facilities, such as transport and storage facilities, mines, power stations, and process plants, and their success depends, among other factors, on the degree to which these facilities support the business objectives. That can be seen as the result of a two-stage process; first the conversion of the objectives into requirements on the facilities, and then the design of facilities to meet those requirements. Both of these processes are prone to inadequacies and even outright errors, as is the transmission of the information across the interface between them. It is an interface between two different cultures, business and engineering, and it is not helped by the fact that the means of transmission, a contractual document of some sort, is developed by a third group, the legal profession, which has a different perspective again.

The problems associated with this process are magnified by the increasing complexity of the requirements. There are several reasons why the complexity is increasing: Most obvious reasons are the size and multi-disciplinary nature of the projects, as well as the technological sophistication made possible by the rapid development of new technology. Another group of reasons arises from the more stringent regulations and requirements with regard to environmental impact and safety. But the most recent and perhaps the most rapidly growing reason is the involvement of community groups of all kinds, made possible by the ready information exchange offered by the Internet. As an example, the design of a high voltage transmission line takes maybe six months, but the community consultation may take several years.

To handle this increasing complexity, the engineering profession has developed systems engineering as a process additional to the traditional, discipline-based (i.e. civil, mechanical, electrical, etc.) design processes and associated management processes. It is perhaps best thought of as a pre-process that reduces the complexity prior to applying the traditional design processes, but it remains involved throughout the whole project. How does it manage to reduce the complexity? By leveraging an observable aspect of how the human brain handles complexity. And it is important to note that complexity is relative to the capabilities of the brain; what is complex to the brain is not complex to a computer, and vice versa. You can instantly recognize your mother on a photograph, something that is a complex task for a computer, but try the cube root of a six-digit number! The observable aspect is that when something has too many variables for the brain to perceive and process it as a unit, we automatically subdivide it into more manageable elements, or chunks. Nowhere is this more obvious than in organizations, e.g. in the military, with the number of soldiers in a platoon, the number of platoons in a company, and so on. This aspect was first made explicit by Prof. George A. Miller in his seminal paper The magical number seven, plus or minus two: Some limits on our capacity for processing information.Psychological Review, 63, 81-97(1956), and a very simple model that provides a possible explanation for why this is so can be found in one of my earlier books, The Changing Nature of Engineering, McGraw Hill (1996).

Systems engineering is the consistent application of this insight to large engineering projects. Such projects contain two complex entities; the physical object to be created, and the work required to create it. Both are treated as systems, i.e. as collections of interacting elements, each organized in a hierarchical structure, so as to maintain the "chunking" introduced above. In the case of the object, the elements are modules, equipment, and subsystems and the structure is called the System Breakdown Structure (SBS) or also system architecture; in the case of the work, the elements are tasks and work packages, and the structure is the Work Breakdown Structure (WBS). In the case of the SBS, the interactions between the elements take the form of a transfer of matter or energy; in the case of the WBS the interactions are in the form of information. Systems engineering consists of a number of processes for developing and managing these structures throughout the project lifecycle, and is documented in such standards as ISO 15288 and EIA 632 or in handbooks, such as the Systems Engineering Handbook published by the International Council on Systems Engineering (INCOSE).

While systems engineering was, for obvious reasons, first developed and employed within the defense and aerospace industries, it is now being increasingly accepted throughout the engineering community as the preferred approach to complex projects, and there is mounting evidence, albeit mainly qualitative and anecdotal, of the benefits that can be achieved. Eric C. Honour, President of Honourcode Inc, has collected data on 44 projects as part of his ongoing efforts to document the value of systems engineering, and one illuminating result is a quantity called Development Quality (DQ) as a function of the proportion of the systems engineering effort spent on a project, as shown in Fig. 1 (reproduced with permission from Understanding the Value of Systems Engineering, in Proceedings of the 14th Annual International Symposium, available online at www.incose.org

Figure 1: Development quality as a function of systems engineering effort.

In this figure, DQ is defined as the inverse of the average of the actual cost (AC) to planned cost (PC) and actual schedule (AS) to budgeted schedule (BS), or

and the systems engineering effort is the product of the actual cost of performing the traditional systems engineering task and a measure of the quality of that performance, expressed as a percentage of the project cost up to delivery of first article, not including production costs.

However, even though systems engineering has improved the success rate of large engineering projects, there are still projects where the proponents of the business venture are less than satisfied with the outcome. Based on my own experience and through discussions with colleagues, in most of these cases the problem has not been in the engineering as such; the facilities have performed exactly as they were designed to do, in accordance with the requirements. On closer inspection, the cause of the dissatisfaction could be traced to the requirements in the first place; i.e. to the expression of the business objectives as requirements on a particular facility. And it is not so difficult to see how this can quite easily happen. From the business point of view, the project is primarily an investment opportunity based on providing a service (in the widest sense, including goods) to meet a perceived market need. The characteristics of the service, its cost, reliability, flexibility in the face of changing market needs, environmental impact, etc, are all of great interest and the subject of detailed modeling and analysis, but how the service is provided is of secondary interest. If it could be provided by a fairy waving her wand (for an acceptable price), that would in principle be equally as satisfactory as building a facility. The facility is, in essence, the engineer's solution to producing the service, and so the interface between the two parts of the development process, the business process and the engineering process, should ideally be the definition of the required service, without tying it to any particular facility.

The purpose of an engineered object is an abstract concept, describing only the service it is intended to provide, completely disassociated from how it does it and from any physical aspects of the object. This is best illustrated by means of a simple example - removing the cork from a bottle of wine. That is the service required by the user; the physical solution provided by engineers may take many different forms, such as a simple cork screw, a cork screw combined with some mechanism for extracting the cork using a smaller amount of force, a thin, hollow needle attached via a valve to small pressurised gas cylinder, a two-pronged device which is inserted between the cork and the bottle, and so on. For any one of these we can give a description of what the object is, by means of drawings, etc., that would allow it to be manufactured without any knowledge of what its purpose is. We could also give a description of how it works, e.g. in the case of the simple corkscrew by means of such parameters as how many turns are required, what torque is required, how much force is required to extract the cork, etc., and this would allow us to determine if it actually fulfils its purpose, i.e. meets the service requirements. These two descriptions would, of course, both be different for different solutions, but all the solutions have in common their purpose, the service they are intended to provide, also called their functionality. I emphasize the inclusion of the word "intended” here; functionality is not a property of any object; it exists prior to any object created to provide the corresponding service.

Now, this is all very well, but in reality it is impossible to get a business venture off the ground without having carried out a bankable feasibility study, which of necessity involves selecting a particular means of producing the service. This selection represents a transition from the space of services to the space of facilities that can provide services, and it is in this transition that we can often find the cause of dissatisfaction with the end result. In the above case of removing a cork the choices are relatively limited (although there would be thousands of variants if all combinations of shape, material, and color were considered); in the case of a major technology-based business venture the number of possible realizations is mind-numbing.

The approach most often taken is to select a few options based on previous experience and identify the preferred option by its greater cost-effectiveness. As effectiveness is defined in terms of meeting the business objectives, it would appear that nothing has been lost in this transition, but a closer scrutiny reveals that, almost invariably, the objectives have been recast using the features describing the performance of the chosen realizations. Again, a very simple example may be the best way to illustrate this: Laundering of clothes is a significant activity in our society; providing that service (i.e. getting our clothes laundered) therefore presents a potential investment opportunity. Our thoughts then automatically focus on the physical activity of laundering, and from there it is only a small step to focus on providing a better washing machine. There are many options, both with regard to technology and with regard to manufacturing, marketing, and sales, and an appropriate application of systems engineering will efficiently find a near-optimal solution in terms of cost-effectiveness. But the effectiveness is now couched in terms of the washing machine's performance, not in terms of meeting the business objective, which was to maximize the return on investment. Once this has taken place, other options, such as providing a laundry service and dispensing with home washing machines all together, are removed from consideration.

The problems surrounding this transition form business to engineering are well recognized, and in my own sector of engineering, consulting, a great deal of attention is directed towards "understanding the needs of the Client”. However, this usually takes place at a point in the life of the project where the Client has already cast his requirements in the form of requirements on a facility, and the engineer is left to, at best, try to understand the underlying business objectives by some form of "reverse engineering” of the requirements. A much better approach would be to apply the analytical, top-down systems engineering approach from the very start of the project, developing the business objectives step-wise in increasing detail, starting with the single objective of maximizing the return on investment. This approach, which can be thought of as design in the functional domain, is the subject of my recent book, Designing Complex Systems, CRC Press (2008).

There is, of course, at some point still a transition from the business objectives into the space of realizations of these objectives, but because this takes place within the same framework, there is always complete traceability back to the business objectives. Even down to the level of detailed design, the justification for any choice from a set of options is formulated in terms of the business objectives, and the business proponent's satisfaction with the outcome is assured.

Finally, with regard to this assurance, I note that systems engineering is very similar to quality assurance. People and enterprises did high-quality work long before there was any talk of quality systems; what a quality system provides is the assurance that a task will be performed to the same standard (almost) every time. Similarly, complex projects were previously, and some still are, undertaken successfully without systems engineering; what systems engineering provides, besides increasing the efficiency of the process, is the assurance that the business objectives will be fully met (almost) every time.

Reforming Weapon Systems Acquisition

Source: AP/Gerald Herbert

Senators Carl Levin (D-MI) and John McCain (R-AZ) have demonstrated that United States Department of Defense spending reform is important enough to merit bipartisan action by co-sponsoring S. 454, the Weapon Systems Acquisition Reform Act of 2009. This legislation could be a step toward creating a more cost-efficient Department of Defense.

The Government Accountability Office identified the weapons acquisition process within the DoD as being at high risk for waste, fraud, abuse and mismanagement in 1990. Nearly 20 years later, the weapons acquisition process has deteriorated even further as contracts have become less competitive and exorbitant cost growth has become the norm. From 2000 to 2007, major military acquisitions ran over budget by $401 billion. The Weapons Systems Acquisition Reform Act would help ensure that interventions occur before the cost-overruns happen in the first place.

Featured Society: NDIA Systems Engineering Division

Source: NDIA Website


The National Defense Industrial Association (NDIA) is a non-profit, educational association representing U.S. industry, government, and all military services. NDIA provides a legal and ethical forum for the exchange of information between Industry and Government on U.S. National Security issues.

The mission of the NDIA Systems Engineering Division is to promote the widespread use of systems engineering (SE) in the United States Department of Defense (DoD) acquisition process, in order to achieve affordable and supportable weapon systems that meet the needs of the military users; to provide a forum for the open exchange of ideas and concepts between government, industry and academia; and to develop a new understanding of a streamlined SE process.

NDIA formed the Systems Engineering (SE) Division over 10 years ago to address technical and management issues related to DoD acquisition reform, and to promote an integrated and balanced approach to weapon system design.

The SE Division seeks to effect good technical and business practices within the aerospace and defense industry. It focuses on improving delivered system performance, including supportability, sustainability, and affordability. The division emphasizes SE excellence in such areas as engineering processes, use of COTS, open systems architecture, SE disciplines, developmental test and evaluation (DT&E), supportability, education & training, modeling and simulation, software, integrated diagnostics, prognostics and enterprise health management, affordability, system assurance, system safety and human systems integration, and overall quality.

The SE Division is supported by Mr. Gordon M. Kranz, Director, Systems and Software Engineering (SSE), in the Office of the Deputy Under Secretary of Defense for Acquisition and Technology. Mr. Kranz's responsibilities include establishing OSD SE and DT&E policy and guidance in support of major DoD acquisition programs. He leads DoD efforts to revitalize SE and DT&E through enhanced SE and integrated T&E practices. Related SSE initiatives include early SE engagement, SE for Systems of Systems, technical risk management, manufacturing and production quality, software engineering, and system assurance.

SSE provides SE and DT&E support to acquisition programs through targeted program assessments that identify issues and risks early in the acquisition cycle in order to provide recommendations to improve program outcomes. The SSE team also manages the associated Defense Acquisition Workforce Improvement Act (DAWIA) competency models and certification standards that affect more than 50,000 members of the acquisition workforce assigned to the SE; production, quality, and manufacturing; and T&E career fields.

The NDIA SE Division is organized to support these U.S. DoD activities and initiatives. Active SE Division committees include Systems Engineering Effectiveness; Systems-of-Systems Engineering, Mission Assurance, Education & Training; Modeling and Simulation; Quality and Reliability Assurance; Life Cycle Support; Automatic Test; Software; System Assurance; Enterprise Health Management including Integrated Diagnostics & Prognostics; Developmental Test & Evaluation; Interoperability & Net-Centric Operations; System Safety; Human Systems Integration; and Quality Assurance.

The SE Division has taken on a number of lead roles and major projects in support of key DoD initiatives. It is the industry sponsor of the DoD/industry Capability Maturity Model Integration (CMMI®) project, which involved restructuring the previously stand-alone Software Engineering Institute (SEI) capability maturity models into an integrated model. The SE Division hosts the annual Systems Engineering Conference and CMMI® Technology Conference and User Group. The division has performed numerous tasks and studies for OSD and the Services and several tasks for the U.S. Defense Science Board.

INCOSE Technical Operations

Resilient Systems Working Group

http://www.incose.org/practice/techactivities/wg/rswg/

by Alwyn Smit.

Introduction

Last time we looked at INCOSE technical operations in general. This article looks at the Resilient Systems Working Group.

Charter

The purpose of the Resilient Systems Working Group is to use systems engineering principles to enhance the resilience of systems to reduce the likelihood of and to recover from disasters. Resilience is the ability of organizational, hardware and software systems to mitigate the severity and likelihood of failures or losses, to adapt to changing conditions, and to respond appropriately after the fact. The study of system resilience includes the creation of a robust infrastructure that designs, builds, tests, maintains, and operates the system. The scope is larger than design, reliability, human factors or system safety. It is an infrastructure wide topic to include customers, developers, suppliers, and all other stakeholders. System resilience has a large interest in cultural, sociological and psychological causes of human-made disasters. Hence, it is truly multidisciplinary. The Resilient Systems Working Group is a part of the INCOSE Public Interest Sector.

Leadership

Chair: Scott Jackson, University of Southern California

Co-Chair: Rick Dove, Stevens Institute of Technology

Contact Resilient Systems Working Group for additional information or to join this group.

Accomplishments and Products

The Resilient Systems Working Group (RSWG) had a successful meeting in Albuquerque with 16 participants. Most of the time was spent discussing what resilience is and reviewing a presentation on resilience. This presentation summarized conclusions from Challenger, Columbia, Chernobyl, 9/11, Katrina and other events. Resilience is the ability of organizational, hardware and software systems to mitigate the severity and likelihood of failures or losses, to adapt to changing conditions, and to respond appropriately after the fact. This definition has not been officially adopted by the group. Such concepts as emergence, complexity and adaptability figure heavily in resilience. The group discussed many products but decided that first priority would be given to a lexicon and to an expanded bibliography. The Resilient Systems Working Group is a node in the international Resilience Engineering Network. The group also has a relationship with the Robust Systems Working Group of the Association Française d'Ingénierie Système (AFIS), the French equivalent of INCOSE.

The URL for the Resilience Engineering Network is: www.resilience-engineering.org. The Proceedings for the Second Symposium on Resilience Engineering in November of 2006 in Juan-les-Pins, France can be found on this site.

The book Resilience Engineering: Concepts and Precepts can be ordered from Ashgate Publishing Limited from the following site: www.ashgate.com.

Current Projects

Technical Operations also include an Internal Operations element that focuses on technical events, technical communications, planning, procedures and publications. Specifically:

  1. Resilience Lexicon. Project Leader - Rick Dove. This project will capture the unique words and definitions associated with resilience.
  2. Expanded Resilience Bibliography Project Leader - Duarte Gonçalves. This project will document the many articles and books associated with resilience. It will also provide a short paragraph describing the content and value of each article or book.
  3. Resilience Report Project Leader - Scott Jackson. The purpose of this project will be to develop a report on resilience that will be understandable by the public and political decision makers. This is a long-term project and will follow the completion of the Lexicon and the Expanded Bibliography.

Latest News

The RSWG, the Anti-Terrorism WG and the Infrastructure WG met in San Francisco with members of the San Francisco Fire Department (SFFD) and discussed the resilience of the fire protection infrastructure system.

Jennifer Maxwell, a student at USC, wrote a paper about the meeting. The idea is that this paper will be the starting point for an article in INCOSE Insight magazine. Additions to the article can be made by those who were there including members of the SFFD. Jennifer, David Boyd and Dick Emerson will be the co-authors of the paper.

Soft Computing Based Modeling in Intelligent Systems

Balas, Valentina Emilia; Fodor, János; Várkonyi-Kóczy, Annamária R. (Eds.)
Publisher: Springer, 2009, ISBN: 978-3-642-00447-6

Publishers Description: The book includes soft computing implementations of intelligent systems models. The recent popularity of fuzzy systems, neural networks and evolutionary computation, considered as related in AI, are now widely used to build intelligent systems. Professor Lotfi A. Zadeh has suggested the term "Soft Computing" for all new techniques working in these new areas of AI. Soft Computing techniques are tolerant to imprecision, uncertainty and partial truth. Due to the large variety and complexity of the domain, the constituting methods of Soft Computing are not competing for a comprehensive ultimate solution. Instead they are complementing each other, for dedicated solutions adapted to each specific problem. Hundreds of concrete applications are already available in many domains. Model based approaches offer a very challenging way to integrate a priori knowledge into procedures. Due to their flexibility, robustness, and easy interpretability, the soft computing applications will continue to have an exceptional role in our technologies.

Business Object Modeling - an Introduction

By Alex P on March 9th, 2009

Business object modeling describes a static representation of the business domain under consideration in a project. It is static as it shows the important entities, their relationships and attributes but does not show how these change over time (see Use Cases - an Introduction for an example of a technique for a ‘dynamic' or functional view of a system).

Thinking in Systems: A Primer

by Donella Meadows

Publisher: Chelsea Green Publishing (December 3, 2008), ISBN-10: 1603580557, ISBN-13: 978-1603580557

Publishers Description

In the years following her role as the lead author of the international bestseller, Limits to Growth—the first book to show the consequences of unchecked growth on a finite planet— Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001.

Meadows' newly released manuscript, Thinking in Systems, is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Edited by the Sustainability Institute's Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life.

Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking.

While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner.

In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.

The Foundations & Pragmatics of Cognitive Work Analysis

by Gavan Lintern, Cognitive Systems Design, Edition 1.0

Synopsis: Cognitive Work Analysis is notoriously difficult for those who encounter it for the first time. It is a complicated and expansive system of analysis, differing in scope and strategy from much of what currently goes on in cognitive engineering. There is little to do about this; the system is what it is for good reasons. Given that state of affairs, we need cohesive, pedagogical accounts of this analytic framework to guide beginners through their early efforts.

Cognitive Work Analysis remains difficult to understand and to execute because we have not made the foundational theory behind it sufficiently explicit and also because we have not been sufficiently tutorial in our approach to explaining it. In believing that these two things go together, I outline the theoretical basis for this framework of analysis and then offer a tutorial example that shows how the concepts can be applied.

Although I offer some refinements of Cognitive Work Analysis, there is nothing fundamentally new in this book. Rather, this is an effort to assemble the important ideas of Cognitive Work Analysis into a treatment that encourages solid understanding via a process of establishing specific concepts as knowledge anchors and then expanding that knowledge into a comprehensive system.

Standards and Guides

ISO/IEC 15288:2008
Systems and software engineering - System life cycle processes

The publishers of this standard state:

ISO/IEC 15288:2008 establishes a common framework for describing the life cycle of systems created by humans. It defines a set of processes and associated terminology. These processes can be applied at any level in the hierarchy of a system's structure. Selected sets of these processes can be applied throughout the life cycle for managing and performing the stages of a system's life cycle. This is accomplished through the involvement of all interested parties, with the ultimate goal of achieving customer satisfaction.

ISO/IEC 15288:2008 also provides processes that support the definition, control and improvement of the life cycle processes used within an organization or a project. Organizations and projects can use these life cycle processes when acquiring and supplying systems.

ISO/IEC 15288:2008 concerns those systems that are man-made and may be configured with one or more of the following: hardware, software, data, humans, processes (e.g., processes for providing service to users), procedures (e.g., operator instructions), facilities, materials and naturally occurring entities. When a system element is software, the software life cycle processes documented in ISO/IEC 12207:2008 may be used to implement that system element.

ISO/IEC 15288:2008 and ISO/IEC 12207:2008 are harmonized for concurrent use on a single project or in a single organization.
