OV-6c – Operational Event-Trace Description

Download PDF

The OV-6c provides a time-ordered examination of the exchanges between participating nodes in a particular scenario. There may be multiple OV-6c products to represent different scenarios, and each event-trace diagram will have an accompanying description that defines the particular scenario or situation.

Usage

The intended usage of the OV-6c includes:

  • Analysis of operational events.
  • Sequences of interactions between nodes.
  • Behavioural analysis.
  • Identification of non-functional user requirements (input to URD).
  • Operational test scenarios.

Product Description

OV-6c allows the tracing of interactions in a scenario or critical sequence of events and can be used by itself or in conjunction with OV-5, Operational Activity Model, and/or an OV-6b to describe the dynamic behaviour of nodes in a mission or operational thread.

UML sequence diagram is used to model OV-6c. The items across the top of the diagram are node instances. Each node has a vertical timeline associated with it. Specific points in time can be labelled running down the left-hand side of the diagram. Directed lines between the node time lines represent interactions (e.g. information exchanges) between nodes, and the points at which they intersect the timelines represent the times at which the nodes become aware of the events.

Creating an Operational Event-Trace Description diagram

To create an Operational Event-Trace Description diagram:

  1. Click on Operational Event-Trace Description in the Action Artifact area, and then select Create New Diagram.
  2. Type the diagram name and press Enter.
  3. A blank diagram is created and you can start constructing the view.
