Making software reuse work: an implementation model

Despite software reuse's promise to significantly improve software quality and productivity, its practice remains elusive. The difficult issues outside the technical realm are seldom addressed. To be practical, reuse must address not only technical but managerial, economic, performance, cultural, and technology transfer issues. A model for implementing software reuse programs is discussed and supported by successful experiences. This model is based on an incremental strategy and addresses the above issues, directly and indirectly. The approach is practical, effective, and has potential to make reuse a regular practice in the software development process. Portions of the model have been used successfully in consulting with SPC member companies.
