The purpose of the Services to Operational Activities Mapping subview is to provide traceability by illustrating which services support which operational activities. In other words, it forms the traceability link between operational view and the service-oriented view.

The NSOV-3 subview shows which operational activities are supported by which services through the use of a mapping matrix. This subview is similar to other mapping matrices in NAF, for example, NCV-5 (Capabilities x System Deployments), NCV-6 (Capabilities x Operational Activities), NCV-7 (Capabilities x Services), NSV-5 (System functions x Operational activities), and NSV-12 (Systems x Services). Together, with these mapping subviews, NSOV-3 forms a line of reasoning that interrelates capabilities, operational (functional) activities, services and systems, through the use of traceability links.
