4.4.3 Extending Platforming to the Sequential Development of System Families

Abstract

Abstract Creating system designs that efficiently satisfy an evolving set of needs is critical for improving program lifecycle properties such as cost, development time, and risk; properties that are often in conflict with near‐term system requirements. This paper proposes that system evolution can be viewed as a family of sequentially developed systems and that existing work in the platforming domain serves as a useful foundation. An overview of related work is provided with emphasis on the platforming literature in an attempt to strengthen the connection between the systems engineering and product platforming communities. A classification scheme is proposed for multi‐system design strategies. Preliminary cost model work is presented, with the ultimate goal being a model that provides program managers with a clear understanding of the economic trades associated with sequential platform development and alternative strategies.
