Implementing Model-Based Product Line Engineering to Manage a Mixed Portfolio of Legacy, Upgrade, and New Development Systems for Self-Propelled Howitzer

This paper summarizes the benefits, technical approach, and lessons learned from applying a Model-Based Product Line Engineering (MBPLE) approach to manage a mixed portfolio of systems at Project Manager (PM) Self-Propelled Howitzer Systems (SPHS) within Program Executive Office (PEO) Ground Combat Systems (GCS). The theme of the paper is to marry the concepts of Model-Based Systems Engineering (MBSE), flexible acquisition strategies, and product line engineering to describe the approach that STC has assisted PM SPHS in implementing for their program office’s digital transformation initiative. Lessons learned, best practices, and economic benefits of utilizing MBPLE are highlighted throughout.
