The U.S. Department of Defense (DoD) is in the midst of a far-reaching transformation affecting joint warfighting concepts as well as business and planning practices. Current government guidance establishes DoD policy for managing Information Technology (IT) investments as portfolios to improve business and warfighting outcomes and capabilities. Integrated architectures, based on the DoD Architecture Framework (DoDAF), are an integral component of DoD IT Portfolio Management (ITPM).
At present, architecture-based investment decisions are not prevalent in the DoD. Our research will formalize the development of dynamic "measures of merit" using executable architecture models derived from integrated architectures. These measures, in combination with value assessments and investment cost estimates, will be used within a portfolio analysis model to assess the optimum portfolio of investments based on total portfolio cost and mission-level value (or benefit) within given constraints (e.g., budget). Integrated architecture-based portfolio investment analysis will enable a robust analytical foundation for capability and architecture-based investment decisions and fully support critical DoD transformation goals, guidelines, and policies.
This paper will discuss how we develop integrated and executable architecture models and our toolset environment, provide an overview of portfolio investment analysis and our portfolio analysis tool, and present the way we will link the architecture and portfolio models. A summary of our research is provided at the conclusion of the paper.
