DoD Architecture Framework
Overview

Federal Policy/Guidance on Architectures
• Information Technology Management Reform Act (1996)
mandates that Chief Information Officers of Executive
Agencies are responsible for “developing, maintaining,
and facilitating implementation of sound and integrated
information technology architecture for the executive
agency”
• OMB Circular A-130 defines Enterprise Architecture as
“the explicit description and documentation of the current
and desired relationships among business and
management processes and information technology”

Architecture Definition
• Architecture
“The structure of components, their relationships, and the
principles and guidelines governing their design and
evolution over time.”
DoD Integrated Architecture Panel, 1995, based on IEEE STD 610.12
“An architecture is the fundamental organization of a
system embodied in its components, their relationships to
each other, and to the environment, and the principles
guiding its design and evolution.”
IEEE STD 1471-2000

DoD Architecture Framework (DoDAF)
Purpose
• An architecture framework is a tool
– It should describe a method for designing an
information system in terms of a set of building
blocks and for showing how the building
blocks fit together.
– It should contain a set of tools and provide a
common vocabulary.
– It should also include a list of recommended
standards and compliant products that can be
used to implement the building blocks.

DoD Architecture Framework
• DoDAF provides guidance on describing architectures in
order to standardize this method of description
– Standardized architecture description approaches improve
possibilities for architecture consistency and reuse
• An architecture description is a representation of:
– a current or future point in time,
– a defined “domain” in terms of its component parts,
• what those parts do,
• how the parts relate to each other, and
• the rules and constraints under which the parts function
October 27, 2004

DoD Architecture Framework
• DoD Architecture Framework is partitioned into
two volumes and a deskbook
– Volume I provides definitions, guidelines, and related
background material
– Volume II contains descriptions and
examples/templates for each of the 26 products
– The Deskbook provides supplementary information to
Framework users
– All three available on Internet at
http://www.aitcnet.org/dodfw/

DoD Architecture Framework
Overview

DoD Architecture Framework
• DoDAF supports development of interoperating
and interacting architectures
• DoDAF defines three related views of an
architecture and products describing each of
these views
• Operational View
• Systems View
• Technical Standards View
October 27, 2004
DoD Architecture Framework
Overview
10
DoDAF Operational View
• Operational View (OV) is description of tasks and
activities, operational elements, and information
exchanges required to accomplish DoD missions
• OV contains graphical and textual products that comprise
an identification of the operational nodes and elements,
assigned tasks and activities, and information flows
required between nodes
• OV defines types of information exchanged, frequency of
exchange, which tasks and activities are supported by the
information exchanges, and nature of information
exchanges
October 27, 2004
DoD Architecture Framework
Overview
11
DoDAF Systems View
• Systems View (SV) is set of graphical and textual
products that describes systems and interconnections
providing for, or supporting, DoD functions
• SV associates systems resources to the Operational
View
– These system resources support operational activities and
facilitate exchange of information among operational nodes
October 27, 2004
DoD Architecture Framework
Overview
12
DoDAF Technical View
• Technical View (TV) is minimal set of rules governing
arrangement, interaction, and interdependence of system
parts or elements
• TV provides technical systems implementation guidelines
upon which engineering specifications are based,
common building blocks are established, and product
lines are developed
• TV includes collection of technical standards,
implementation conventions, standards options, rules,
and criteria organized into profiles that govern systems
and systems elements for a given architecture

C4ISR Architecture Framework Example
• In order to demonstrate examples of the
contents of some of the DoD Architecture
Framework products, assume that we will
analyze the application domain for a Border and
Coastline Surveillance System (BCSS) that
should provide aerial coastline and border
surveillance and reporting for the United States
Border Patrol and Drug Enforcement Agency

16
Overview and Summary Information Product
(AV-1)
• The Overview and Summary Information
Product (AV-1) of the DoD Architecture
Framework is used to document the
Identification, Purpose, Scope, Intended Users,
and Context of the system or system-of-systems
that is being described.
October 27, 2004

17
Overview and Summary Information Product
(AV-1) for BCSS
1. Identification – The BCSS is to be developed for the
Department of Homeland Security to meet the BCSS
mission roles.
2. Purpose – The BCSS will employ autonomous, longendurance drone aircraft to patrol both land and water
border regions in order to detect unauthorized incursions
and notify ground personnel.
3. Scope – The BCSS development project will develop,
demonstrate, integrate, deliver, and maintain the air
vehicle, ground station, mission planning, and logistics
functionalities that comprise BCSS.

Overview and Summary Information Product
(AV-1) for BCSS
4. Intended Users – BCSS will be used by the U.S. Border
Patrol and the Drug Enforcement Agency to monitor the
borders and coastal waters to detect possible
unauthorized incursions into the United States and to
notify authorities to investigate these incursions.
5. Context – BCSS is to be a system that employs an
autonomous, long-endurance drone aircraft capable of
integration into civilian airspace and of sharing
surveillance data with other aircraft as well as with its
mission monitoring station.

Integrated Dictionary Product (AV-2)
• The Integrated Dictionary Product (AV-2) of the DoD
Architecture Framework is to define terms used in the
given architecture
• AV-2 consists of textual descriptions in form of glossary,
repository of architecture data, their taxonomies, and
their metadata (data about architecture data)
• AV-2 enables set of architecture products to stand alone,
allowing them to be read and understood with minimal
reference to outside resources

High-Level Concept Graphic Product
(OV-1)
• The High-Level Concept Graphic Product (OV-1)
of the DoD Architecture Framework is used to
depict a high-level graphical description of the
proposed system and its internal and external
interdependencies.
• OV-1 serves as a facilitating diagram for
explaining the system elements and interfaces
and for showing the system’s role as an element
of the encompassing system-of-systems.

Product (OV-2)
• The Operational Node Connectivity Description Product
(OV-2) of the DoD Architecture Framework is used to
depict the operational nodes and elements of the
architecture, the needlines between them, and the
characteristics of the information exchanged.
• OV-2 serves as a facilitating diagram for further defining
the interfaces and information to be exchanged and for
showing the system’s role as an element of the
encompassing system-of-systems
• OV-2 is frequently done at both the system-of-systems

Operational Information Exchange Matrix
(OV-3)
• The Operational Information Exchange Matrix
(OV-3) of the DoD Architecture Framework
details information exchanges and identifies who
exchanges what information, with whom, why the
information is necessary, and how the information
exchange must occur
• OV-3 identifies information elements and relevant
attributes of information exchange and
associates the exchange to the producing and
consuming operational nodes and activities and
to the needline that the exchange satisfies
October 27, 2004
DoD Architecture Framework

Operational Information Exchange Matrix
(OV-3)

Conclusion
• Our DoD customers are being instructed to
describe their system architectures for milestone
review meetings using DoDAF products
• Some Boeing programs are using DoDAF
products in their documentation
– J-UCAS has an Architecture Description Document
that uses DoDAF products to capture their system
architecture
Boeing systems engineers need to become familiar with
developing and using the DoDAF products
