Architecture evolution and evaluation (ArchEE) capability

IT Architectures, rather than being static, must now constantly evolve and adapt to changes driven by new technologies, increasing business partnerships, and end-user expectations. In addition, continuously increasing architecture complexity demands for a rigorous evaluation of performance. ArchEE™, a BPMN model-based systems engineering capability, fulfills the emerging SoSE need of making informed evolution decisions of mission oriented IT architectures in a timely manner. The ArchEE model structure facilitates simultaneous evolutions of operational and systems architecture components by different stakeholders. It also enables rapid integration of component models for alternative architectures for a specific mission and its evaluation via simulation. ArchEE uses the same model for qualitative and quantitative analysis throughout the SoSE process. This paper describes and illustrates the ArchEE capability via Fire and Counter-fire battle management scenarios, comparing the mission effectiveness of the new design against the existing systems.
