Summary	The Navy's open architecture framework is intended to promote reuse and reduce costs. However, current approaches to software acquisition require reusable software components to be retested each time they are used in a new context, which is a major contributor to cost per instance of reuse. The proposed research focuses on exploiting open architectures principles to safely reduce testing costs for reusable software components. Software components that are reused without modification need to be retested in some, but not necessarily in all cases in. This project will investigate conditions under which testing of unmodified components can be safely avoided, methods for identifying situations in which retesting can be safely reduced, and policies on how to effectively focus retesting in cases where some retesting is needed.
