Each year, INCOSE's technical team recognizes the best papers of the symposium. The following are abstracts from the award winners from 2006. The complete text of each of these papers can be found on the symposium proceedings CD.
Evolution of a Standard - EIA-632 from 1994 to 2006
Paper 2.4.1 by Rich Harwell
Process standards represent the best practices used by an industry or discipline. Most process standards are usually created by volunteer teams operating under the auspices of an authorized standards development body such as the Government Electronic and Information Technology Association (GEIA). This paper examines the evolution of one standard from its inception in 1994 to its current revision activities, noting the factors influencing scope, content, and structure. It also provides an insight into the latest decisions affecting the current revision efforts.
Meeting the Challenge of Knowledge-Creating Systems
Paper 4.3.1 by James Martin
Many systems help us increase our knowledge of the world in one way or another. Business application systems help managers understand the marketplace and how best to address market needs. Military systems provide command and control capabilities so we can have better battlefield awareness so we can fight to win. Chemical processing facility systems help us gain awareness of what is happening all along the processing chain. If all these systems help us gain knowledge of the world, does SE have the tools to analyze the knowledge-creation capacity of our systems? This paper will explore that question.
Lessons Learnt from the Application of QFD to the Definition of Complex Systems
Paper 5.3.1 by Amihud Hari, Joseph Kasser, and Menachem Weiss
Quality Function Deployment (QFD) has been used to elucidate and negotiate requirements for at least 20 years. QFD has a lot to offer but when used to specify complex systems, has been found to have a number of deficiencies, has been perceived as a time consuming process and has been found as being difficult to apply to complex systems. This paper summarizes the top five lessons learned from 15 years of experience in using QFD in the elicitation, elucidation and negotiation of requirements for complex systems.
Identification of Real Options ‘in’ Projects
Paper 8.1.3 by Richard de Neufvillel and Tao Wang
The concept of real options - initiated in the field of finance - has extended into engineering systems to model design flexibility in the realistically uncertain environment. However, whereas financial options are well-defined traded contracts, real options “in” engineering systems are a priori undefined, complex, and interdependent. Moreover, systems involve many more options than designers could consider. Therefore designers need to identify the real options most likely to offer good flexibility and the most value.
This paper proposes a procedure to identify real options “in” engineering systems. It consists of a screening and a simulation model. The screening model is a simplified, conceptual, lowfidelity representation of the system that reflects its most important issues. As it is inexpensive to run, it is used to test extensively designs under dynamic conditions. The following simulation model is used to validate critical considerations, such as the robustness and reliability of the designs, which are omitted from the screening model in order to expedite its operation. 119 The paper first establishes the concepts of the options identification model, and then resorts to examples to detail its application. The case of a hydro power system formulates the screening and simulation models, and presents the specific steps needed to search systematically for the interesting real options.
The FAR Approach: Functional Analysis/Allocation and Requirements Flowdown Using Use Case Realizations (Brian Mar Award for Best Student Paper)
Paper 7.2.1 by Kjell Borg, Jürgen Börstler, and Magnus Eriksson
This paper describes a use case driven approach for functional analysis/allocation and requirements flowdown. The approach utilizes use cases and use case realizations for functional architecture modeling, which in turn form the basis for design synthesis and requirements flowdown. We refer to this approach as the FAR (Functional Architecture by use case Realizations) approach. The FAR approach is currently applied in several largescale defense projects within BAE Systems Hägglunds AB and the experience so far is quite positive. The approach is illustrated throughout the paper using the well known Automatic Teller Machine (ATM) example.
