A Risk-Driven Process Decision Table to GuideSystem Development Rigor

摘要

The Incremental Commitment Model (ICM) organizes systems engineering andrnacquisition processes in ways that better accommodate the different strengths and difficultiesrnof hardware, software, and human factors engineering approaches. As with other modelsrntrying to address a wide variety of situations, its general form is rather complex. However, itsrnrisk-driven nature has enabled us to determine a set of twelve common risk patterns andrnorganize them into a decision table that can help new projects converge on a process that fitsrnwell with their particular process drivers. For each of the twelve special cases, the decisionrntable provides top-level guidelines for tailoring the key activities of the ICM, along withrnsuggested lengths between each internal system build and each external system incrementrndelivery. This paper elaborates on each of the twelve cases and provides examples of their use.
