Model-based systems engineering (MBSE) has received much attention in the past few years; however, few have discussed how to use the models themselves as part of the review process. The assumption was that the MBSE tools would produce the necessary documentation and then the review process would proceed as usual. This approach limits the utility of MBSE as suggested changes will be lost in the paper shuffle between the review and the model. It also takes additional time to produce the paper documentation and capture the results. In addition, reviewers will not see the entire model and they will be unable to query the model to determine how good or complete it is. Recently, Stevens Institute of Technology and NASA have been exploring how to use only the MBSE repository as a means to conduct reviews. This paper summarizes some of the lessons learned from conducting these reviews. It also provides insights on how tool developers can do a better job of supporting model-based reviews.
