Architecture supports SE by providing a structured approach to document design and
development decisions based on established requirements.
Planning, Programming, Budgeting, and Execution
The PPBE process allocates resources within the DoD and establishes a framework and
process for decision-making on future programs. PPBE is a systematic process that guides
DoD’s strategy development, identification of needs for military capabilities, program
planning, resource estimation, and allocation, acquisition, and other decision processes.

DoDAF Introduction
http://cio-nii.defense.gov/sites/dodaf20/background.html[3/3/2011 3:33:50 PM]
JCIDS is a key supporting process for PPBE, providing prioritization and affordability advice.
DoDAF V2.0 supports the PPBE process by identifying the touch points between architecture
and the PPBE process, identifying the data to be captured within an Architectural
Description, facilitating informed decision-making, and identifying ways of presenting data to
various stakeholders/roles in the PPBE decision process.
Portfolio Management
DoD policy requires that IT investments be managed as portfolios to ensure IT investments
support the Department’s vision, mission, and goals; ensure efficient and effective delivery
of capabilities to the Warfighter; and maximize return on investment within the enterprise.
Each portfolio may be managed using the architectural plans, risk management techniques,
capability goals and objectives, and performance measures. Capability architecting is done
primarily to support the definition of capability requirements. PfM uses the Architectural
Description to analyze decisions on fielding or analysis of a needed capability.
Architectural support to PfM tends to focus on the investment decision itself (although not
exclusively), and assists in justifying investments, evaluating the risk, and providing a
capability gap analysis.
Operations
In most cases, an enterprise will capture its routine or repeatable business and mission
operations as architectural content. However, when the basic structure of an activity is very
stable and the activity repeated often, such as military operations planning or project
definition and management, the enterprise may choose to include that structure as part of
the Architectural Description itself. In this case, the architecture repository may be enhanced
to include templates, checklists, and other artifacts commonly used to support the activity.
The JCIDS, PPBE, and DAS processes establish a knowledge-based approach, which requires
program managers to attain the right knowledge at critical junctures to make informed
program decisions throughout the acquisition process. The DoD IT PfM process continues to
evolve that approach with emphasis on individual systems and/or services designed to
improve overall mission capability. Consistent with OMB Capital Planning and Investment
Control (CPIC) guidance, the DoD uses four continuous integrated activities to manage its
portfolios – analysis, selection, control, and evaluation. The overall process is iterative, with
results being fed back into the system to guide future decisions.

DM2 Support for the Six Core Processes DoDAF Supports
The DoDAF V2.0 Meta-model Groups support the viewpoints and DoD Key Processes of
JCIDS, DAS, PPBE, System Engineering, Operations, and Portfolio Management (IT and
Capability). The table below indicates a non-inclusive mapping of DoDAF Meta-model Groups
to the DoDAF Viewpoints and DoD Key Processes. The support for the Key Processes is for
the information requirements that were presented at the workshops for the key processes
and, as such, do not reflect all of the information requirements that a key process could
need.
