About this diagram


When modelling Air Campaign Planning (ACP), it is not sufficient to represent
the activities which take place, their order, and the resources which they
use. Multi-perspective modelling frameworks such as CommonKADS and the
Information Systems Architecture remind us that it is also important to define
WHO performs these activities, and WHERE it is necessary to communicate
information between these agents. 

In order to present this information, we have chosen to use a Role Activity
Diagram (RAD). The RAD shows which agents perform particular processes, and
shows all information which must be communicated between agents as labelled
links. In the diagram shown, each senior officer and each planning cell is
treated as a separate agent (yellow rectangle). The diagram
shows all the activities which are performed (white squares) and all the
interactions which take place (labelled links) between the issuing of a JFC's initial
instructions to a JFACC and the production of an Air Tasking Order (ATO).

Wherever an interaction takes place, information (often in the form of
a document) passes from one agent to another. The links between agents
are labelled to show what information is being passed between agents.
For example, the Recommended Defense Posture is produced by the Air
Strategy planning cell and is communicated to the JFACC. If a piece of
information (e.g. the recommended JIPTL) is passed to several agents,
then the activity which produces that piece of information is labelled
with an X.

Information is also communicated witin an agent, particularly if that
agent is a planning cell. The extent to which this occurs can be
determined by examining the inputs and outputs of activities. For
example, the broad weaponeering assessment performed by the Intel Plans
cell requires the potential target list, previously produced by the
same planning cell, as input.
