Evolution of the ReqMan Framework

The ReqMan Framework is considered a theoretical, coarse structuring of concepts related to Requirements Engineering. For this purpose, the concepts of requirements phases, practices, and techniques were introduced in a first iteration, and defined based on a study of the literature. The first version of the Framework was evaluated in different application contexts with a focus on those practices that are considered the central instrument, with the intention of identifying potential optimization regarding its use. It became clear during the course of the evaluation that on the one hand, there are large differences between the practices developed with regard to their granularity, and, on the other hand, that these practices also permit ambiguous interpretations. In particular, across SMEs, the number of practices (47) was not manageable. Based on the results of the evaluation steps, a second evolution phase of the Framework (Framework 2.0) was developed and implemented. This report describes the results of the evaluation as well as the second evolution phase of the ReqMan Framework.
