A single source of truth. This is one of the most used and most overloaded terms in model-based systems engineering – perhaps second only to “model” itself. A clear and compelling objective on the surface, it is shorthand representing an aspiration for project teams and a benefit of adopting MBSE. …

By David Long, Vitech President Just like simplicity, not all precision is helpful. Heresy? Not for engineers. Engineers are taught to use the appropriate degree of precision for the circumstance at hand. Unfortunately, as systems engineers, we too often forget those lessons. The quest for precision can lead us astray, …

In Romeo and Juliet, Shakespeare famously wrote “a rose by any other name would smell as sweet.” In the case of systems engineering and the drive to models, …
