Chapter 4 of the INCOSE Systems Engineering Handbook (4th ed.) provides a thorough discussion of “Technical Processes for the System Lifecycle.” The first two technical processes are (i) business or mission analysis and (ii) stakeholder needs and requirement definition. Each of these processes leverages engagement of system designers with business …

By David Long, Vitech President “The biggest errors are made on day one.” Sadly, those involved in systems engineering live this every day, but not necessarily in the manner we think. Though we strive to avoid this pitfall and address it in the systems we develop, the very way we …

By Ron Kratzke, Principal Systems Engineer In a previous post entitled “Variant Management in an MBSE Environment,” I covered the techniques used in CORE and GENESYS to capture variants in the physical architecture. In this post, I will cover techniques to capture variants of the behavior architecture and development of …

When teaching classes on model-based systems engineering, I am frequently asked about methods to manage different system configurations in the model. Most engineers are very comfortable thinking in part structures, and while this is a critical aspect of systems engineering, it’s not the whole story. To answer the question and …
