Defense Acquisition System
The DAS exists to manage the nation’s investments in technologies, programs, and product
support necessary to achieve the National Security Strategy and support employment and
maintenance of the United States Armed Forces. The DAS uses Joint Concepts, integrated
architectures, and DOTMLPF analysis in an integrated, collaborative process to ensure that
desired capabilities are supported by affordable systems and other resources.
DoD Directive 5000.1 provides the policies and principles that govern the DAS. In turn, DoD
Instruction 5000.2, Operation of the DAS establishes the management framework for
translating mission needs and technology opportunities, based on approved mission needs
and requirements, into stable, affordable, and well-managed acquisition programs that
include weapon systems and automated information systems (AISs). The Defense Acquisition
Management Framework provides an event-based process where acquisition programs
advance through a series of milestones associated with significant program phases.
The USD (AT&L) leads the development of integrated plans or roadmaps using integrated
architectures as its base. DoD organizations use these roadmaps to conduct capability
assessments, guide systems development, and define the associated investment plans as the
basis for aligning resources and as an input to the Defense Planning Guidance (DPG),
Program Objective Memorandum (POM) development, and Program and Budget Reviews.
Systems Engineering
DoD Acquisition policy directs all programs responding to a capabilities or requirements
document, regardless of acquisition category, to apply a robust SE approach that balances
total system performance and total cost with the family-of-systems, and system-of-systems
context. Programs develop a Systems Engineering Plan (SEP) for Milestone Decision
Authority (MDA) that describes the program’s overall technical approach, including activities,
resources, measures (metrics), and applicable performance incentives.
SE processes are applied to allow an orderly progression from one level of development to
the next detailed level using controlled baselines. These processes are used for the system,
subsystems, and system components as well as for the supporting or enabling systems used
for the production, operation, training, support, and disposal of that system. Execution of
technical management processes and activities, such as trade studies or risk management
activities may point to specific requirements, interfaces, or design solutions as non-optimal
and suggest change to increase system-wide performance, achieve cost savings, or meet
scheduling deadlines.
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 invest
