A Method for Guiding Software Evolution

We present an approach to guide the process of adjusting existing software to new or changed requirements in a sys tematic way. The approach relies on a set of intermediate artifacts linked by mappings that bridge the gap between re quirements 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 applica tion.
