The Software Technology for Adaptable, Reliable Systems (STARS) program has articulated a mission to accelerate the shift to a ``process-driven, domain-specific reuse-based, technology-supported'' development paradigm for software-intensive DOD systems. In support of this mission, the three STARS' prime contractors (Boeing, IBM, and Unisys) are jointly developing a description of the reuse aspects of such a software development paradigm. This description is captured in an evolving document called the STARS Reuse Concept of Operations. The focus of version 0.5 [1], a recently-released first draft, is a framework for considering and defining reuse supporting process building blocks and for composing these building blocks into broader contexts such as reuse-based organizational strategies and product life cycles. The remainder of this paper gives an overview of that reuse process framework.
