Architecture Frameworks and Modeling
Speaker Dr. James Martin, Ph.D, INCOSE Fellow Abstract Architecture frameworks and modeling are tools developed to meet the challenges of architecting modern systems. In particular, DoDAF, the “Department of Defense Architecture Framework,” is an architecting tool that has been mandated by the DoD for large-scale systems. “Mandated” is easily understood, but some of the affectations of DoDAF are not so easily understood. The framework “…describes how the architecture for a system...should be documented. The framework breaks that documentation into three major views: operational, system, and technical, and one associated view, the all view. Each view contains one or more graphic, tabular, and descriptive representations of the system. Because using any framework for the first time can be difficult…” (news@sei website). According to the DoD Architecture Framework Version 1.5 (DoD document at defenselink.mil website), “Architectures within the Department of Defense are created for a number of reasons. From a compliance perspective, the DoD is compelled… to develop architectures. From a practical perspective, experience has demonstrated that management of organizations employing sophisticated systems and technologies in pursuit of joint missions demands a structured, repeatable method for evaluating investments and alternatives, implementing organizational change, creating new systems, and deploying new technologies.” This tutorial provides an overview of the architecture frameworks and models with an emphasis on DoDAF. The tutorial will show how a system’s architecture serves as the basis for development of the system. This approach leads to a more model-driven systems approach and allows the systems engineers to "discover" the essential attributes of the problem space that must be addressed by the system solution. Architecture models define these essential attributes and facilitate their evaluation. The architecture provides the unifying structure (or roadmap) for exploration of the problem space and for characterization of the solution space such that better decisions can be made. This tutorial will describe an approach for the flow down from the system purpose or mission need, down through operational requirements and concept of operations, and finally into the operational, system, and technical views of the architecture. The 26 products in the DOD Architecture Framework will also be described while highlighting the essential features of each. Biography Dr. James Martin is an internationally renowned writer and lecturer on systems engineering. He wrote one of the most widely read books on systems engineering, Systems Engineering Guidebook. His experience includes twenty years in systems development of telecommunications products (most with Bell Labs) as program manager, systems engineering manager, system architect, requirements manager, and lead systems engineer. His experience with technology includes mobile wireless, fiber optics, satellite broadband wireless, reconnaissance sensors and distribution networks, and airborne hubs. He led the development of ANSI/EIA 632, the national standard defining the processes for engineering a system. He teaches at The Aerospace Institute and at seminars around the world. Dr. Martin graduated with an M.S. from Stanford and a B.S. from Texas A&M. His Ph.D. research at Geroge Mason University was on “Enterprise Architecture Modeling Using Knowledge Modeling.” He is an INCOSE Fellow. Location July 18 |
