Abstract:
Model-based engineering (MBE) in industry is on the rise. However, improvements are still needed on the oversight and management of MBE efforts. Frequently, program managers and high-level decision makers do not have background in MBE to understand models, the value the models are providing, and if they are successfully achieving their MBE goals. To address these concerns, we developed a rating scale for models, called Model Assurance Levels (MALs). The purpose of the MALs is to be able to quickly and concisely express the assurance the model is providing to the program, as well as, risks associated with the model. Therefore, given a MAL level, program managers and decision makers will be able to quickly understand the model value and risks associated with the model. They can then make informed decisions about the future direction of MBE development effort.
