A Risk-Driven Process Decision Table to Guide System Development Rigor

摘要

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