Improving Reviews by Extended Traceability

Year 1999

When defining a new system, the history and functionality of the system to be replaced should be considered. Thereby making the same failure twice or neglecting important system functionality can be avoided. The requirements of the existing system are typically elicited by analysing concrete system usage scenarios. The requirements are typically being represented using conceptual models. To establish conceptual models of high quality, reviewing the models is common practice. The problem faced with when reviewing conceptual models, is that the reviewer can not assess and therefore understand the basis (concrete system usage) on which the conceptual models where build. In this paper, we present an approach to overcome this problem. We argue to establish extended traceability, by recording concrete system usage scenarios using rich media (e.g. video, speech, graphic) and interrelating the recorded observations with the conceptual models. We discuss the principle improvements for reviewing processes result-ing from the extended traceability and illustrate the advantages with excerpts of the case study performed in a mechanical engineering company.
