During product development, engineers are called on to provide a design solution to a particular problem. We are also asked to document the journey along the way for the purpose of being able to retrace our steps when issues arise. I once had an engineer tell me that it was …

In the world of model-based systems engineering (MBSE), there is still a fair amount of confusion around what makes a good—or even acceptable—MBSE model. George E. P. Box, the English statistician, famously observed, “All models are wrong, but some are useful.” He further clarified that idea with this expansion, “Remember …

In the past few months I’ve been writing about how to model basic SysML concepts of behavior using GENESYS. SysML has three largely separate approaches for modeling behavior: activities, interactions, and states. I’ve covered the modeling of behavior using activities and interactions in August (Modeling SysML Activities in GENESYS) and …

Modeling behavior in SysML can be painstaking and difficult to communicate to a broad range of stakeholders. Fortunately, GENESYS makes it easy to use SysML constructs in a way that facilitates a comprehensive and consistent behavioral model and makes it easier to discuss with a broad range of stakeholders. What …
