From The MODAF Acquisition (AcV) Viewpoint p2:

From The MODAF Acquisition (AcV) Viewpoint p2:

The AcV-1 depicts logical groupings of projects (into “clusters”), mapped to the organisations that manage them, in order to describe the portfolio of projects that contribute to a coherent acquisition programme. It provides a means of identifying the main dependencies between acquisition elements.

This view provides a means of analysing the main dependencies between acquisition elements.

From The MODAF Acquisition (AcV) Viewpoint p2:

The AcV-1 provides a way of describing the organisational relationships between multiple acquisition projects that deliver individual systems or capabilities as part of a wider programme. Consequently, it generally will not be developed by those building Architectures for an individual project.

In essence, AcV-1 is an organisational breakdown consisting of actual organisations (see OV-4, Operational Relationships Chart) in a hierarchical structure which groups the projects they manage to form acquisition clusters.

The view is strongly linked with StV-4, Capability Dependencies, which shows capability clusters and dependencies.

The intent of an AcV-1 is to show:

  • All of the acquisition projects delivering capability within the programme of interest.
  • The structure of acquisition projects.

An AcV-1 is specific to a particular Enterprise Phase – i.e. the structure of programmes may change over time as projects are merged, axed and the capability portfolio rebalanced. Hence, it is possible that an acquisition programme could have more than one AcV-1, each showing how the acquisition clusters are arranged for relevant Enterprise Phases.
