A METHOD FOR GUIDING SOFTWARE EVOLUTION

摘要

We present an approach to guide the process of adjusting existing software to new or changed requirements in a systematic way. The approach relies on a set of intermediate artifacts linked by mappings that bridge the gap between requirements and code. Those artifacts and the links between them can be constructed and maintained with reasonable effort. Additional support is supplied by bookkeeping and validation concepts. We demonstrate the usefulness of our approach by performing our method on a real-life application.
