Evaluation of Model-Based Systems Engineering processes for integration into rapid acquisition programs

This thesis describes a framework upon which programs, particularly those identified as engaging in rapid acquisition, can compare themselves to determine if the adoption of a Model-Based Systems Engineering (MBSE) approach might be feasible. The research was established as a case study of several defense acquisition programs that are using MBSE as part of their software development process by providing a background for those programs being evaluated, then delving into their individual MBSE processes to identify the principal elements that added the most value in terms of delivering a suitable and effective product expediently. After completing the characterization of the MBSE approaches, an assessment of a sample target program was conducted, exercising the framework developed. The research indicates that while the implementation of MBSE can require additional effort during the initial development stages, the demonstrated benefits typically outweigh the extra upfront burden by reducing the overall design cycle time and improving the validation and verification activities. An in-depth mapping of the upfront MBSE work required would provide additional engineering rationale to justify the programmatic investment for implementing an MBSE approach.http://archive.org/details/evaluationofmode1094550550Outstanding ThesisCivilian, Naval Undersea Warfare Center Division, Newport, Rhode IslandApproved for public release; distribution is unlimited
