This thesis proposes a model-based systems engineering (MBSE) methodology to be implemented post Milestone C, develops a Microsoft Excel MBSE analysis tool which provides a recommendation to implement MBSE, and provides a case study for implementing MBSE post Milestone C on a Department of Defense (DoD) acquisition program. The purpose of the MBSE methodology is to identify how MBSE should be implemented post Milestone C to address the systemic challenges which are faced by DoD acquisition programs post Milestone C. The Excel MBSE analysis tool provides a set of questions which provide metrics to the program office to determine the benefit of implementing MBSE post Milestone C into their program. The thesis then details, through a case study, how the Excel MBSE analysis tool can be used to decide whether to implement MBSE. Prior research on the systemic challenges within DoD acquisition programs as well as the use of MBSE during post Milestone C activities were leveraged in developing the proposed MBSE methodology and Excel MBSE analysis tool. The thesis makes a recommendation to implement MBSE post Milestone C to mitigate schedule, cost, and risk uncertainties. This is done through digitally linking various models, such as a manufacturing model and a logistics model to an integrated master schedule (IMS). Based on the metrics and cost, the Excel MBSE analysis tool provides a recommendation on which models should be implemented.
