In the acquisition of a software-intensive system, the relationship between the software architecture and the acquisition strategy is typically not carefully examined. To remedy this lack, a research team at the Carnegie Mellon University Software Engineering Institute SEI has focused a multiyear effort to discover an initial set of failure patterns that result when these entities become misaligned and identify a set of desired relationships among the business and mission goals, system and software architectures, and the acquisition strategy. This report describes the result of the third year of the SEI s research, where the team defined a method that indicates such areas of misalignment i.e., between a program s architecture and acquisition strategy. The alignment method is used as early in a program s lifetime as practical, ideally before the architecture or acquisition strategy has attained full definition. The authors illustrate the method by means of a case study, during which many of the key elements of the method were piloted.
