Domain analysis: a systems approach to software reuse

A process for a systems approach to domain analysis that forms the foundation for a reuse-directed developments process is presented. A domain analysis is the systems engineering of a family of systems in an application domain. The end goal of a domain analysis is to build and maintain a reuse library asset which can be used to develop instances of systems in the domain family. A three-phase approach is recommended for performing the domain analysis: model the domain, architect the domain, and develop software components. All products of the domain analysis activities are reusable in future system developments in the family, and also in the analysis of related domains. It is concluded that domain analysis, when done right, is a significant undertaking. It does, however, produces a significant benefit
