Systems engineering competencies for enterprise transformation

This paper examines the relationship between enterprise transformation competencies and systems engineering competencies. We analyze a systems engineering competency model with respect to enterprise transformation competencies to show that many systems engineering competencies provide a solid foundation for providing an organization with an organic capacity to successfully accomplish enterprise transformation. A systems engineering career competency model developed by the Department of the Navy is described and shown to be part of a holistic approach to strategic workforce management, and which accounts for competencies needed for enterprise transformation.

Comprehensive use case scenario generation: An approach for modeling system of systems behaviors

This paper describes a reusable approach using automatic use case scenario generation to specify system of systems (SoS) behaviors. The approach leverages the Monterey Phoenix (MP) language and tools which extend current methods significantly by making a larger number of SoS use case scenario variants available to SoS analysts. Having described how MP structures behavior models to accomplish this task in previous papers this paper provides model-building details and advice that takes readers through the approach so they may repeat it on a SoS of their own interest. A simplified SoS model of three systems interacting in a humanitarian assistance and disaster relief (HADR) scenario is used to demonstrate the approach. The HADR example highlights the model structure features that enable automatic SoS use case scenario generation and supporting descriptions of each part of the model are provided. The paper concludes with a summary and brief discussion of ongoing research areas that support bringing this approach into the mainstream of system of systems engineering practice.
