The mission of the STARS program is to stimulate and accelerate the transition into practice of productivity-and quaiity-enhancing benefits from emerging software pro ce ss and reuse technologies.Process technology development and transfer activities in STARS are organized to present a conceptual model [see Figure 1] of process insertion, usage, and improvement that will achieve process-driven development in organizations developing criticai software systems. This model addnmes the interactions between major participants in processprocess definers, process users, process improvers, and those responsible for institutionaiizing effective processes. Key constituents of the model (and hence, activities in STARS) are a process asset library, process definition technology, process enactment (use) support, process measurement technology, and process evolution concepts. The SEI'S process concepts provide the context and industry expectations for process technology which STARS is fostering, and the SEI leads the joint STARS/SEI process Asset Library activity.STARS emphasizes automated support for process technology (meaning tools supporting the emerging role of process engineer) in evolving, commercially supported software engineering environments. Because Ada systems development is the primary target of STARS technology, STARS is sponsoring formaiizations of Ada process models and reuse processes that take advantage of Ada. Figure 1.
