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 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

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)
