Chapter 5: Systems Engineering Processes

In this chapter, the focus will be on one of the fundamental aspects of systems engineering and, therefore, model-based systems engineering – the process.

Understanding processes is key to understanding systems engineering. Remember that systems engineering describes an approach to realizing successful systems. One of the main applications of process modeling is to understand approaches to doing things, therefore it is not surprising that processes lie at the heart of a good systems engineering approach. In fact, it is a framework alongside a set of processes that provide the overall model-based systems engineering (MBSE) approach that is described in this book. Think back to the MBSE diagram from Chapter ...
