DoD Architecture Framework (DODAF)

AETM 012

DAU GLOSSARY DEFINITION

Alternate Definition

The DoD Architecture Framework (DoDAF) provides the structure for organizing architecture concepts, principles, assumptions, and terminology about operations and solutions into meaningful patterns to satisfy specific DoD purposes. It enables the sharing and reuse of architectural data.

General Information

The DoD Architecture Framework (DoDAF) Version 2.02 facilitates the ability of Department of Defense (DoD) managers at all levels to make key decisions more effectively through organized information sharing across the department, Joint Capability Areas (JCAs), mission, component, and program boundaries The Framework contains 8 viewpoints (comparable to DoDAF V1.5 “views”), and 52 models (comparable to DoDAF V1.5 “products”). DoDAF provides a standard framework for developing architectural views and capturing and presenting architectural data that supports systems engineering and the sharing of technical information among stakeholders across systems of systems and the DoD Enterprise.

A model of the Department of Defense Acquisition Framework including the following viewpoints: All Viewpoint, Data and Information Viewpoint, Standards Viewpoint, Capability Viewpoint, Operational Viewpoint, Services Viewpoint, Systems Viewpoint and Project Viewpoint

The key terms of DoDAF Version 2.02 are:

Model DoDAF-described Model:

  • Serve as a template for organizing and displaying data
  • Easily understood format
  • Can be documents, spreadsheets, dashboards, or other graphical representations

View: Data collected and presented as a "filled-in" model

Viewpoint: Organized collection of views

Architecture Description: All Viewpoints together

DoDAF Meta Model (DM2): Provides information needed to collect, organize, and store data in a way easily understood. DM2 is organized into three levels:

  • Conceptual Data Model  
  • Logical Data Model
  • Physical Exchange Specification

Physical Exchange Schema (PES): Logical Data Model generated as an XML Schema Description

Fit-for-Purpose: User-defined views (subset of architectural data) created for a specific purpose.

DoDAF Conformance

DoD Components are expected to conform to DoDAF to the maximum extent possible in development of architectures within the Department. Conformance ensures that reuse of information, architecture artifacts, models, and viewpoints can be shared with common understanding. Conformance is expected in both the classified and unclassified communities, and further guidance will be forthcoming on specific processes and procedures for the classified architecture development efforts in the Department.

DoDAF conformance is achieved when:

  • The data in a described architecture is defined according to the DM2 concepts, associations, and attributes.
  • The architectural data is capable of transfer in accordance with the PES.
