Software reuse: From library to factory

Abstract

Systematic software reuse is a key business strategy that software managers can employ to dramatically improve their software development processes, to decrease time-to-market and costs, and to improve product quality. Effective reuse requires much more than just code and library technology. We have learned that careful consideration must be given to people, process, and technology. One approach to the systematic integration of these three elements is the concept of the software factory. At Hewlett-Packard Co., we have initiated a multifaceted corporate reuse program to help introduce the best practices of systematic reuse into the company, complemented by multidisciplinary research to investigate and develop better methods for domain-specific, reuse-based software engineering. This essay discusses our experiences. Key aspects include domain-specific kits, business modeling, organization design, and technology infrastructure for a flexible software factory.
