At first blush it is tempting to look at this book and ask, “How does this have any relevance for systems engineering?” After all, this little volume was first published in 1940 by an “ad man.” It’s 75 years old and predates the recognition of systems engineering as a separate …

When considering the adoption of model-based approaches and techniques, organizations frequently ask “what is the biggest challenge we will face?” It is a good question, one that deserves a good answer. While model-based systems engineering (MBSE) is clearly the future of systems engineering, adopting model-based approaches is not trivial. To …

By Ron Kratzke, Vitech Principal Systems Engineer Recently I have fielded several questions regarding the use of the State Transition Diagram in CORE and how States/Modes and the diagram relate to system behavior and simulation of the system behavior using CORESim. State transition diagrams describe the logical transition of a …

By Sara Sumner, Vitech Applications Engineer As a systems engineer, I have found that when working with complex projects, it is critically important to capture the relationships between the product and the functional work allocation. Capturing these relationships can help manage the uncertainty of impacts on the project when inevitable …
