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

Implications for GIG/SOA and MS COI

• The development of the Global Information Grid
  (GIG) and its service oriented architecture (SOA)
• The concerns of the MS COI must eventually be
  expressed within the appropriate DoDAF views.
• The services offered by the MS 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 MS support

Service Offering Life Cycle in SOA Environment

• Services
• at multiple levels
• in multiple phases
• under pressure to be delivered quickly

Conclusions

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