This report describes operational concepts and implementation strategies for the Design Configuration Management Process (DCMP). It presents a process-based systems engineering model for the successful configuration management of the products generated during the operation of the design organization as a business entity. The DCMP model focuses on Pro/E and associated activities and information. It can serve as the framework for interconnecting all essential aspects of the product design business. A design operation scenario offers a sense of how to do business at a time when DCMP is second nature within the design organization.

This paper describes an approach that was developed to produce structured models that graphically reflect the requirements contained within a text document. The document used in this research is a draft policy document governing business in a research and development environment. In this paper, the authors present a basic understanding of why this approach is needed, the techniques developed, lessons learned during modeling and analysis, and recommendations for future investigation. The modeling method applied on the policy document was developed as an extension to entity relationship (ER) diagrams, which built in some structural information typically associated with object-oriented techniques. This approach afforded some structure as an analysis tool, while remaining flexible enough to be used with the text document. It provided a visual representation that allowed further analysis and layering of the model to be done.

As part of the High Consequence System Surety project, this work was undertaken to explore, one approach to conducting a surety theme analysis for a software-driven system. Originally, plans were to develop a theoretical approach to the analysis, and then to validate and refine this process by applying it to the software being developed for the Weight and Leak Check System (WALS), an automated nuclear weapon component handling system. As with the development of the higher level High consequence System surety Process, this work was not completed due to changes in funding levels. This document describes the software analysis process, discusses its application in a software, environment, and outlines next steps that could be taken to further develop and apply the approach to projects.
