Title: 
 

Systematic Literature Review: How is Model-Based Systems Engineering Justified? 

​

Abstract:   

​

The change process, investment, training, and tools needed to implement a model-based systems engineering (MBSE) approach across the engineering enterprise are substantial. How is the change from a document-based systems engineering approach (DBSE) to a model-based systems engineering approach (MBSE) justified? 

The primary conclusion from a literature review is that there is a significant advantage to project performance by applying an MBSE approach. An MBSE approach made the engineering processes on a complex system development effort more efficient by improving requirements completeness, consistency, and communication. These were seen in engineering processes involved in requirements management, concept exploration, design reuse, test and qualification, Verification and Validation, and margins analyses. 

An MBSE approach was most effective at improving defect prevention strategies. The approach was found to enhance the capability to find defects early in the system development life cycle (SDLC), when they could be fixed with less impact and prevented rework in later phases, thus mitigating risks to cost, schedule, and mission.

 

Bio:  

 

Edward R. Carroll (Ed) is a Principal R&D Systems Research Analyst at Sandia National Laboratories. His research is in digital engineering approaches. His 40-year background includes expertise in systems sciences, systems engineering, software engineering and enterprise computing. His domain expertise includes military systems, nuclear weapons and processes, and commercial enterprise systems and processes. his focus is on understanding the optimal application of advanced engineering approaches, such as digital enterprise (model-based engineering), and the application of augmented intelligence to meet Sandia’s strategic nuclear weapons engineering objectives. 

​

Prior to working at Sandia, Ed led projects and programs to automate business and technical decisions through analytic models for economic performance analyses and merchandise optimization, improved processes for manufacturing and supply-chain management through statistical process control, and statistical comparisons of medical (clinical) procedure effectiveness. Ed directed his own consultancy for 14 years as well as providing leadership in executive roles in business development and technology, including roles as vice president of engineering for Egghead.com, director of technology at Nike, and director of software engineering at Boeing (serving the Hanford Nuclear Reservation). 

​

Additionally, Ed is a retired Naval Aviator and an accomplished musician. He received a BA in Liberal Art from Arizona State University, an MS in Systems Management from the University of Southern California, and a Graduate Certificate in BioMedical Informatics from Oregon Health Sciences University. He lives with his wife, Barbara, in Albuquerque, NM.
