Influences on M&S COI Tasks

1. M&S Services at the Crossroads of Service Oriented Architecture and the DoD Architectural Framework Bernard P. Zeigler, Ph.D.,Arizona Center for Integrative Modeling and SimulationandJoint Interoperability Test CommandFort Huachuca, AZ 85613-7051zeigler@ece.arizona.edu

2. Influences on M&S COI Tasks M&S Body of Knowledge MetaData M&S Theory and Framework Mediation DoD Architectural Framework Services

3. DoD Architectural Framework (DoDAF) • DoD mandate requires that the DoD Architectural Framework (DoDAF) be adopted to express high level system and operational requirements and architectures. • DoDAF is the basis for the integrated architectures mandated in DOD Instruction 5000.2 and provides broad levels of specification related to operational, system, and technical views. • Operational views capture the requirements of the architecture being evaluated • System views provide its technical attributes

4. Implications for GIG/SOA and M&S COI • The development of the Global Information Grid (GIG) and its service oriented architecture (SOA) • The concerns of the M&S COI must eventually be expressed within the appropriate DoDAF views. • The services offered by the M&S COI must be architected within the DoDAF operational views • Obstacles: • The DoDAF essential approach is that of systems orientation rather than service orientation • The DoDAF expresses interest in development of executable architectures but does not explicitly elucidate M&S support

5. Correlating Development Life Cycle Phases with DODAF Views Planner Owner Designer Implementer Contractor Operator (not in DODAF) Actors (DODAF People/IO) Phases of life cycle DODAF view products Concept Analysis Design Develop Test Deploy Maintain For each phase in life cycle, associate the relevant actors and from there, the relevant DODAF View Products

6. Community-wide Enterprise Services COI Enterprise Services CORE Enterprise Services Service Offering Life Cycle in SOA Environment • Services • at multiple levels • in multiple phases • under pressure to be delivered quickly

9. Conclusions • Correlating DoDAF with SOA Life Cycle Development process and M&S is not straightforward • DoDAF needs elaboration with service oriented views • To support M&S needs • elaboration of downstream life cycle • integration of verification testing along cycle • integration of evaluation along cycle (connection with NR-KPP)
