Spiral Acquisition of Software-Intensive Systems of Systems.

The Department of Defense and other organizations are finding that the acquisition and evolution of complex systems of systems is both software-intensive and fraught with old and new sources of risk. This article summarizes both old and new sources of risk encountered in acquiring and developing complex software-intensive systems of systems. It shows how these risks can be addressed via risk analysis, risk management planning and control, and application of the risk-driven Win-Win Spiral Model. It will also discuss techniques for handling complicating factors such as compound risks, incremental development, and rapid change, and illustrates the use of principles and practices with experience in applying the model to the U.S. Army Future Combat Systems program and similar programs.
