Abstract: In their paper on “A Generalized Systems Engineering Reuse Framework and Its Cost Estimating Relationships,” (Wang, Roedler, et al. 2014) present an approach for estimation of systems engineering effort that extends the COSYSMO equation to account for the effort associated with Design With Reuse and Design For Reuse classification categories in the Generalized Reuse Framework. Implementation of this approach for cost estimation clearly depends on two critical items: (1) the ability to accurately and consistently count the size drivers; and (2) the ability to calibrate the model equation. As part of future work, they also describe the potential to use this approach as a management tool in architecture development – “a cataloging mechanism in organizing components of reference architecture.” This paper presents a practical implementation of the COSYSMO cost estimating relationship through extension of a Model Based Systems Engineering (MBSE) modeling environment with SysML for estimating end-to-end systems engineering effort in developing a system. The approach provides a new way of rapidly creating cost estimates, conducting cost-based analysis and trade studies with full traceability from the cost estimation parameters back to the architecture of referenced system of interest.
Bio: Barry Papke is the Director of Professional Services for No Magic Inc. and actively teaches and consults worldwide on Model Based Systems Engineering (MBSE), system design with SysML and enterprise architecture development with DODAF/UPDM. Prior to joining No Magic, he spent thirty-two years as a systems engineer, operations analyst and program manager with L-3 Communication, Raytheon and Lockheed Martin. Barry is an active member of the INCOSE Agile and Security Working Groups and participates each year in the International Workshop and International Symposium. He also works with other INCOSE chapters around the US supporting/participating in local chapter workshops and events. Barry has a Bachelor of Science in Mechanical Engineering from Texas A&M University and a Master of Science in Systems Engineering from Steven’s Institute of Technology.
