UNDERSTANDING CHANGING REQUIREMENTS IN THE DEVELOPMENT OF SAFETY CRITICAL SYSTEMS

One of the major and continuing problems within the design profession is the growing significance of evolving or changing requirements during the system life cycle. This paper describes the work being carried out on the PROTEUS project concerned with the looking at the effects of requirements change on systems engineering projects. An overview of the project is given, the motivation and scope, knowledge acquisition methods used and the findings of the task activities are described. Finally, the implications of the findings are discussed.
