Model-based initiatives have been gaining an increasing amount of attention. Model-Based Enterprise (MBE) efforts are focused on mechanical hardware documentation. Model-Based Design (MBD) initiatives are targeted at quicker virtual prototyping cycles for embedded software. Model-Based System Engineering (MBSE) strategies offer a single unambiguous definition for systems design. So far, these three approaches have different definitions, standards, and patron organizations. It seems the only thing they really share is two words in their title. Is there an underlying relationship among the three? Should there be more collaboration between these efforts? How might we be better served by having the three constituencies work together? What are the steps to make it happen?
