| This paper discusses and illustrates a multidiscipline approach of analyzing and engineering transformational solutions as we migrate to a network centric force. The approach is based on and utilizes state-of-the-art System, Architecture and Modeling & Simulation (M&S) engineering theories, concepts and practices. From a foundational perspective, this paper provides an overview of the relationships between these engineering disciplines, the use of integrated Department of Defense (DoD) Architecture Framework (DoDAF) based architectures, the utilization of decision support theory and the application of Modeling & Simulation (M&S). These concepts serve as a rigorous means of achieving System of System (SoS) interoperability. This methodology presents a rigorous integrated approach which drives system engineering based solutions, obtains realistic application & performance profiles, supporting the insertion of technology while providing the insights necessary to facilitate the transformation. The contributions of the paper are far reaching and include: a multifaceted integrated engineering approach, an illustrated set of examples which shows in an increasing level of detail how these engineering disciplines can be used to develop real world transformational engineering solutions and the use of realistic M&S to measure the AS-IS → TO-BE architectural evolution. Finally, the paper concludes with several areas of crucial research for the future to continue down the path to a fully integrated net centricity force. |
