A requirements engineering testbed: concept, status and first results

A requirements engineering testbed being developed and used by Rome Air Development Center is described. The testbed is used to support the research, development, application, and evaluation of requirements engineering methods and tools. It is based on a novel process model for requirements engineering activities that provides a detailed description of the fundamental activities occurring during requirements engineering and their relationships to design activities. The testbed´s implementation includes a requirements analysis method and two requirements validation techniques based on rapid prototyping and simulation. Each of these tools is described from the perspective of the user, and the status of the testbed is presented. Application of early versions of the prototyping tools in two case studies indicates that significant productivity gains can be realized from using testbed prototyping techniques to validate user interface requirements
