To support these goals system developers must be provided with tools that allow them effectively assess the impact of change across the systems (impact analyses), identify reuse opportunities (reuse analyses), identify gaps in existing system functionalities (gap analyses), and identify redundancies (redundancy analyses). In this paper we discuss some of the issues related to implementing a model-based repository capable of supporting Redundancy, Impact, Gap, and Reuse (RIGR) analyses.enText/Conference Paper1617-5468
