The StV-2 presents capabilities and the hierarchical relationships between them. StV-2 specifies all the capabilities that are referenced throughout one or more architectures – i.e. one StV-2 may provide the definitive list of capabilities for a number of logical and physical architectures. In addition, it can be used as a source document for the development of high-level use cases and Key User Requirements (KURs).
Usage
The intended usage of the StV-2 includes:
- Identification of existing and required capabilities.
- Codifying required capability elements.
- Source for the derivation of cohesive sets of KURs.
- Providing reference capabilities for multiple architectures.
Product Description
The StV-2 specifies a hierarchy of capabilities. A capability taxonomy persists over time (an architect may wish to specify historical, current or future capability) and may be referenced by multiple architectures. The capabilities specified in an StV-2 are extensively re-used in operational, service-oriented, system and acquisition views; in this way the concept of capability is integral to any MODAF architecture.
In MODAF, a capability is a description of an ability to do something. In StV-2, the capabilities are only described in the abstract – i.e. StV-2 does not specify how a capability is to be implemented. An StV-2 is most commonly structured as a specialisation hierarchy of capabilities, with the most general at the root and most specific at the leaves.
Creating a Capability Taxonomy diagram
To create a Capability Taxonomy diagram:
- Click on Capability Taxonomy in the Action Artifact area, and then select Create New Diagram.
- Type the diagram name and press Enter.
- A blank diagram is created and you can start constructing the view. You can create Capabilities and connect them through the tools under the diagram toolbar.
MODAF in Visual Paradigm
The MODAF is brought to you by Visual Paradigm, a full-featured development platform. Visual Paradigm provides an easy-to-use, model-driven MODAF tool that supports the development of MODAF views and models. You can create integrated MODAF products and generate architectural documents that facilitate organizations to efficiently coordinate enterprise architecture initiatives.
