Using Model-Based Systems Engineering Methods to Capture a Department of Defense Acquisition Life Cycle
Abstract
The Office of the Deputy Assistant Secretary of Defense for Systems Engineering (ODASD[SE]) is pushing model-based systems engineering (MBSE) methods to increase efficiencies and technical rigor in Department of Defense (DoD) engineering practices. MBSE methods might also aid in the planning of an acquisition process. An MBSE process is proposed for capturing the acquisition life cycle, the structure that implements the life cycle processes, and the developed information artifacts using a SysML model. The SE processes for an example middle tier of acquisition (MTA) program are modeled and model views of how program information, functions, and developed information artifacts are shown. The MBSE approach with the ability to synchronize information across views and use data queries to extract information into tables or matrixes was found to be beneficial for planning required acquisition life cycle functions, capturing the resources or informational elements the functions need, identifying a national team and required infrastructure, and allocating work breakdown structure (WBS) elements to those team members or infrastructure. The modeling approach allows additional flexibility for programs to extend or modify the processes to meet their specific needs. Additional work is needed to develop methods to simulate and analyze the model for benefits of alternative development approaches.
