OV-02 Operational Resource Flow Description diagrams

You can draw the following symbols on an OV-02 Operational Resource Flow Description diagram:

•Performer, and any of its subtypes, such as Interface (Port), Organization, Performer, Person, Service. Service Interface, or System

The OV-02 can also show the location of Operational facilities or locations, and can optionally be annotated to show flows of information, funding, people, or materiel between Operational Activities.

Note An alternative to the OV-02 Operational Resource diagram is available in System Architect: the OV-02 Operational Resource Alternative diagram enables you to draw not only Performers and Resource Flows between them, but also many other artifact types.

The following artifacts are drawn on the OV-02 Operational Resource Flow Alternative diagram:

Performer is the person or organization that performs an Activity. There are several kinds of performers, such as Person and Organization, but also System, Interface, Service, and Service Interface. All of these kinds of Performer inherit all of their properties from Performer.

You specify the Activity or Activities that a Performer performs through the ActivityPerformedbyPerformer relationship. On the OV-2, you can draw an ActivityPerformedByPerformer line from an Activity to any kind of Performer symbol.

An Activity is work (not specific to a single organization, weapon system, or individual) that transforms inputs (Resources) into outputs (Resources) or changes their state.

You can specify that an Activity is performed by a Performer by drawing an ActivityPerformedByPerformer line from an Activity to a Performer on the OV-02 Operational Resource Flow Alternative diagram.

Information is a type of Resource: it inherits Resource's properties and behavior.

You can relate Capabilities to the Activities that perform them by drawing an ActivityAbletoPerformCapability line from an Activity to a Capability.

The following are types of resources:

You can specify that an Activity effects change on a Resource by drawing an ActivityChangesResource line from an Activity to any kind of Resource (and any kind of Performer since Performer is a subclass of Resource), available on the OV-02 Operational Resource Alternative diagram.

Materiel is a type of Resource. Materiel represents equipment, apparatus, or supplies that are of interest, without distinction as to its application for administrative or combat purposes. You can draw Materiel on the OV-02 diagram, and specify what Activity effects change on Materiel by drawing an ActivityChangesResource line from an Activity to a Materiel symbol.

You can specify that an Activity is able to perform a Capability by drawing an ActivityAbletoPerformCapability line from an Activity to a Capability, available on the OV-02 Operational Resource Alternative diagram.

Any kind of Thing can be described by Information. In the DM2 metamodel, this means that Activity, Resource, or Capability can be described by Information: you can draw a describedBy line from Activity, Resource (and all of its subtypes), or Capability, to the Information symbol (or supertypes such as Resource). The describedBy relationship enables you to specify how the following model types describe one another:

•Any type of Resource describedBy another Resource (for example, you might specify that a Resource is described by an Information type. When you draw the describedBy relationship between a Resource and an Information symbol, then the Resource definition's ListOf Information property is populated accordingly.

•Any type of Performer describedBy any type of Resource (for example, you might specify that a Performer is described by a Resource. When you draw a describedBy relationship from Performer to Resource, the Performer's ListOf Resource property is populated accordingly.
