CV-4 Capability Dependencies

FavoriteLoadingAdd to favorites

 

The CV-4 “Capability Dependencies” describes the dependencies between planned capabilities and also defines logical groupings of capabilities.   It’s intended to provide a means of analyzing the dependencies between capabilities.

The groupings of capabilities are logical, and the purpose of the groupings is to guide enterprise management. In particular, the dependencies and groupings may suggest specific interactions between acquisition projects to achieve the overall capability.

DoDAF Architecture Framework Version 2.02 – Page 122

The intended usage of the CV-4 includes:

  • Identification of capability dependencies.
  • Capability management (impact analysis for options, disposal etc.).

The CV-4 describes the relationships between capabilities. It also defines logical groupings of capabilities. This contrasts with CV-2 “Capability Taxonomy” model which also deals with relationships between Capabilities; but CV-2 only addresses specialization-generalization relationship (i.e., capability taxonomy).

A CV-4 shows the capabilities that are of interest to the Architectural Description. It groups those capabilities into logical groupings, based on the need for those elements to be integrated.

An approach for describing a CV-4 is graphical. In some cases, it may be important to distinguish between different types of dependency. Graphically, this can be achieved by color-coding the connecting lines or by using dashed lines. From a data perspective, the CV-4 can make use pre-existing capability dependency types in the DoDAF Meta-model; else new, specific dependency types can be created. The new dependency types need to be recorded the in the AV-2 “Integrated Dictionary”.

AcqTips:  

  • The DoDAF descriptions in this website are very generic and are mostly taken from the DoDAF Architecture Framework website. Make sure you visit the actual website for the most update information and a more thorough explanation of each viewpoint.
  • DoDAF Version 1.0, although outdated, has some good examples on how to construct AV’s, OV’s, and SV’s.
