Overview
The "Operational View" (OV) in the DoDAF Enterprise architecture framework (version 1/1.5) ('Operational Viewpoint' in DODAF 2) describes the tasks and activities, operational elements, and information exchanges required to conduct operations. A pure Operational View is material independent. However, operations and their relationships may be influenced by new technologies such as collaboration technology, where process improvements are in practice before policy can reflect the new procedures. The operational viewpoint provides a means to describe what is needed in a solution-free or implementation-free way. There may be some cases, however, in which it is necessary to document the way processes are performed given the restrictions of current systems, in order to examine ways in which new systems could facilitate streamlining the processes. In such cases, an Operational View may have material constraints and requirements that must be addressed. For this reason, it may be necessary to include some high-level Systems View (SV) architecture data as overlays or augmenting information onto the Operational View products.DoD Architecture Framework Working Group (2003)Operational View topics

The Department of Defense Architecture Framework (DoDAF) defines a standard way to organize aOV products
The Department of Defense Architecture Framework (DoDAF) has defined a series of seven different types of Operational View products. There are seven OV products described in this section: * High-Level Operational Concept Graphic (OV-1) * Operational Node Connectivity (Resource Flow) Description (OV-2) * Operational Information Exchange (Resource Flow) Matrix (OV-3) * Organizational Relationships Chart (OV-4) * Operational Activity Model (OV-5) * Operational Rules Model, State Transition Description, and Event-Trace Description (OV-6a, 6b, and 6c) * Logical Data Model (OV-7)High-Level Operational Concept Graphic

* Operational Rules Model, State Transition Description, and Event-Trace Description (OV-6a, 6b, and 6c) ** Operational Rules Model (OV-6a) : One of the three products used to describe operational activity sequence and timing that identifies the business rules that constrain the operation. ** Operational State Transition Description (OV-6b) : One of the three products used to describe operational activity sequence and timing that identifies responses of a business process to events. ** Operational Event-Trace Description (OV-6c) : 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. * Logical Data Model (OV-7) : Documentation of the data requirements and structural business process rules of the Operational View.Executable Operational Architecture
In addition to examining behavior over time, one can also assess an overall dynamic mission cost over time in terms of human and system/network resource dollar costs and their processes dollar costs. Analysis of dollar costs in executable architectures is a first step in an architecture based investment strategy, where we eventually need to align architectures to funding decisions to ensure that investment decisions are directly linked to mission objectives and their outcomes. The figure on the right illustrates the anatomy of one such dynamic model. State transitions in executable operational architectural models provide for descriptions of conditions that control the behavior of process events in responding to inputs and in producing outputs. A state specifies the response of a process to events. The response may vary depending on the current state and the rule set or conditions. Distribution settings determine process time executions. Examples of distribution strategies include: constant values, event list, constant interval spacing, normal distribution, exponential distribution, and so forth. Priority determines the processing strategy if two inputs reach a process at the same time. Higher priority inputs are usually processed before lower priority inputs. Processes receiving multiple inputs need to define how to respond. Examples of responses include: process each input in the order of arrival independent of each other, process only when all inputs are available, or process as soon as any input is detected. Processes producing multiple outputs can include probabilities (totaling 100 percent), under which each output would be produced. Histograms are examples of generated timing descriptions. They are graphic representations of processes, human and system resources, and their used capacity over time during a simulation run. These histograms are used to perform dynamic impact analysis of the behavior of the executable architecture. Figure 4-23 is an example showing the results of a simulation run of human resource capacity.See also
