NOV-6c provides a time-ordered examination of the information exchanges between the participating operational nodes of a particular scenario. Each event-trace diagram should have an accompanying description that defines the particular scenario or situation.

The HOPEX NAF models missions and organizational processes via operations. These processes describe who does what to perform missions, regardless the service delivered to the customer. The starting point of the description is an organizational process. This description is done in two ways: either by splitting the organizational process into smaller parts (sub-organizational processes), or by describing how the organizational process is actually performed by the different participants. The participants themselves are designed within the context of the organizational process and are later associated to org-units of the organization. The Organizational Process Diagram is used to detail how the organizational process is performed.
