8th December 2017


The CVp-05 Concept Activity Viewpoint is part of the TRAK Concept Perspective and one of the 21 TRAK Architecture Viewpoints.

The CVp-05 identifies the activities conducted by concept nodes as part of an implementation-free description of the overall concept.

The CVp-05 viewpoint is the specification for the CV-05 Concept Activity View.
