NAF v3: NCV-4 MODAF: StV-4
The C3 view describes dependencies between capabilities. It also defines logical composition of capabilities (i.e. capability clusters).
The C3 is intended to provide a means of analysing the dependencies between capabilities and between capability clusters. The composition of capabilities (into clusters) is logical, and the purpose of the clusters is to guide enterprise management.

- Capability management (impact analysis for options, disposal etc).

Detailed Product Description
The C3 describes the relationships between capabilities. It also defines logical groupings of capabilities. This contrasts with C1 (Capabilities) which also deals with relationships between capabilities; but C1 only addresses specialisation and composition relationships (i.e. capability taxonomy).
The C3 is intended to provide a means of analysing the dependencies between capabilities and between capability clusters. In particular, it will highlight potential integration requirements and the interactions needed between acquisition projects in order to achieve the overall capability.
The recommended notation for C3 is a functional dependency diagram which shows how functions are clustered together and the relationships between the individual functions or clusters of functions. It may also be useful to supplement the functional dependency diagram with a functional n-squared diagram. The following four examples show the same C3 view presented in different ways.
The example above shows simple structure and traceability.
Above is the same information shown in grid form.
The example above is UML, using a composite class diagram approach.
The example above is UML again, but this time using aggregation relationships instead of composite diagrams.
Key Elements and Their Relationships
The data in an C3 can include:
- Capability Dependency (relationship).
- Capability Composition (relationship).
