Topics in Interoperability: Structural Programmatics in a System of Systems James D. Smith 10.1184/R1/6585341.v1 https://kilthub.cmu.edu/articles/report/Topics_in_Interoperability_Structural_Programmatics_in_a_System_of_Systems/6585341 This technical note presents a case study on how choices of structural programmatics (e.g., hierarchical or peer-to-peer organization, centralized or decentralized execution) affect the ability to achieve programmatic interoperability in the context of large, complex systems of systems. Key systems-of-systems concepts and definitions are introduced and explored through the case study. In addition, this report illustrates the pitfalls of focusing on only one aspect of a problem and discusses the need to balance management's desires for control with the realities of systems-of-systems programmatics. This report also introduces an alternative to conventional program management practice that addresses the pitfalls previously identified. 2006-10-01 00:00:00 software engineering technical report
