DoDAF Views
The DoDAF defines a set of products, a view model, that act as mechanisms for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through graphic, tabular, or textual means. These products are organized under four views: Each view depicts certain perspectives of an architecture as described below. Only a subset of the full DoDAF viewset is usually created for each system development. The figure represents the information that links the operational view, systems and services view, and technical standards view. The three views and their interrelationships driven – by common architecture data elements – provide the basis for deriving measures such as interoperability or performance, and for measuring the impact of the values of these metrics on operational mission and task effectiveness.
 * overarching All View (AV),
 * Operational View (OV),
 * Systems View (SV), and the
 * Technical Standards View (TV).

All View (AV)
AV products provide overarching descriptions of the entire architecture and define the scope and context of the architecture. The AV products are defined as:
 * AV-1 Overview and Summary Information - Scope, purpose, intended users, environment depicted, analytical findings (if applicable)
 * AV-2 Integrated Dictionary - Definitions of all terms used in all products.

Operational View (OV)
Operational View (OV) products provide descriptions of the tasks and activities, operational elements, and information exchanges required to accomplish DoD missions. The OV provides textual and graphical representations of operational nodes and elements, assigned tasks and activities, and information flows between nodes. It defines the type of information exchanged, the frequency of exchanges, the tasks and activities supported by these exchanges and the nature of the exchanges. The OV products are defined as:
 * OV-1 High Level Operational Concept Graphic - High level graphical and textual description of operational concept (high level organizations, missions, geographic configuration, connectivity, etc).
 * OV-2 Operational Node Connectivity Description - Operational nodes, activities performed at each node, and connectivities and information flow between nodes.
 * OV-3 Operational Information Exchange Matrix - Information exchanged between nodes and the relevant attributes of that exchange such as media, quality, quantity, and the level of interoperability required.
 * OV-4 Organizational Relationships Chart - Command, control, coordination, and other relationships among organizations.
 * OV-5 Operational Activity Model - Activities, relationships among activities, inputs and outputs. In addition, overlays can show cost, performing nodes, or other pertinent information.
 * OV-6a Operational Rules Model - One of the three products used to describe operational activity sequence and timing that identifies the business rules that constrain the operation.
 * OV-6b Operational State Transition Description - One of the three products used to describe operational activity sequence and timing that identifies responses of a business process to events.
 * OV-6c Operational Event-Trace Description - One of the three products used to describe operational activity sequence and timing that traces the actions in a scenario or critical sequence of events.
 * OV-7 Logical Data Model - Documentation of the data requirements and structural business process rules of the Operational View.

Systems and Services View (SV)
SV is a set of graphical and textual products that describe systems and services and interconnections providing for, or supporting, DoD functions. SV products focus on specific physical systems with specific physical (geographical) locations. The relationship between architecture data elements across the SV to the OV can be exemplified as systems are procured and fielded to support organizations and their operations. The SV products are:
 * SV-1 Systems/Services Interface Description - Depicts systems nodes and the systems resident at these nodes to support organizations/human roles represented by operational nodes of the OV-2. SV-1 also identifies the interfaces between systems and systems nodes.
 * SV-2 Systems/Services Communications Description - Depicts pertinent information about communications systems, communications links, and communications networks. SV-2 documents the kinds of communications media that support the systems and implements their interfaces as described in SV-1. Thus, SV-2 shows the communications details of SV-1 interfaces that automate aspects of the needlines represented in OV-2.
 * SV-3 Systems-Systems, Services-Systems, Services-Services Matrices - provides detail on the interface characteristics described in SV-1 for the architecture, arranged in matrix form.
 * SV-4a/SV-4b Systems/Services Functionality Description - The SV-4a documents system functional hierarchies and system functions, and the system data flows between them. The SV-4 from DoDAF v1.0 is designated as 'SV-4a' in DoDAF v1.5. Although there is a correlation between OV-5 or business-process hierarchies and the system functional hierarchy of SV-4a, it need not be a one-to-one mapping, hence, the need for the Operational Activity to Systems Function Traceability Matrix (SV-5a), which provides that mapping.
 * SV-5a, SV-5b, SV-5c Operational Activity to Systems Function, Operational Activity to Systems and Services Traceability Matrices - Operational Activity to SV-5a and SV-5b is a specification of the relationships between the set of operational activities applicable to an architecture and the set of system functions applicable to that architecture. The SV-5 and extension to the SV-5 from DoDAF v1.0 is designated as 'SV-5a' and ‘SV-5b’ in DoDAF v1.5 respectively.
 * SV-6 Systems/Services Data Exchange Matrix - Specifies the characteristics of the system data exchanged between systems. This product focuses on automated information exchanges (from OV-3) that are implemented in systems. Non-automated information exchanges, such as verbal orders, are captured in the OV products only.
 * SV-7 Systems/Services Performance Parameters Matrix - Specifies the quantitative characteristics of systems and system hardware/software items, their interfaces (system data carried by the interface as well as communications link details that implement the interface), and their functions. It specifies the current performance parameters of each system, interface, or system function, and the expected or required performance parameters at specified times in the future. Performance parameters include all technical performance characteristics of systems for which requirements can be developed and specification defined. The complete set of performance parameters may not be known at the early stages of architecture definition, so it should be expected that this product will be updated throughout the system’s specification, design, development, testing, and possibly even its deployment and operations life-cycle phases.
 * SV-8 Systems/Services Evolution Description - Captures evolution plans that describe how the system, or the architecture in which the system is embedded, will evolve over a lengthy period of time. Generally, the timeline milestones are critical for a successful understanding of the evolution timeline.
 * SV-9 Systems/Services Technology Forecast - Defines the underlying current and expected supporting technologies that have been targeted using standard forecasting methods. Expected supporting technologies are those that can be reasonably forecast given the current state of technology and expected improvements. New technologies should be tied to specific time periods, which can correlate against the time periods used in SV-8 milestones.
 * SV-10a Systems/Services Rules Model - Describes the rules under which the architecture or its systems behave under specified conditions.
 * SV-10b Systems/Services State Transition Description - A graphical method of describing a system (or system function) response to various events by changing its state. The diagram basically represents the sets of events to which the systems in the architecture will respond (by taking an action to move to a new state) as a function of its current state. Each transition specifies an event and an action.
 * SV-10c Systems/Services Event-Trace Description - Provides a time-ordered examination of the system data elements exchanged between participating systems (external and internal), system functions, or human roles as a result of a particular scenario. Each event-trace diagram should have an accompanying description that defines the particular scenario or situation. SV-10c in the Systems and Services View may reflect system-specific aspects or refinements of critical sequences of events described in the Operational View.
 * SV-11 Physical Schema - One of the architecture products closest to actual system design in the Framework. The product defines the structure of the various kinds of system data that are utilized by the systems in the architecture.

Technical Standards View (TV)
TV products define technical standards, implementation conventions, business rules and criteria that govern the architecture. The TV products are as follows:
 * TV-1 Technical Standards Profile - Extraction of standards that applies to the given architecture.
 * TV-2 Technical Standards Forecast - Description of emerging standards that are expected to apply to the given architecture, within an appropriate set of timeframes.
