Many sources have reported that the technical and managerial
maturity of the acquirer is the essential key to success of Software-
Intensive System Acquisition (SISA) and recommended to adopt the best
practices. However, DoD is inactive to implement the SISA practices because
DoD doesn’t fully understand how and why the SISA practices
affect the performance of software-intensive system development.
In this research, we analyze the effects of SISA practices on acquirer
and developer using hybrid software process simulation modeling. Our
approach represents the dynamic characteristics (e.g., the interactions of
acquisition organization and development organization and the effects of
several SISA practices) and discrete characteristics (e.g., specific characteristics
of discrete phase, etc.) of SISA programs. This research will
contribute to reveal how the acquirer’s activities influence the performance
of the developer’s process.
