ABSTRACT
The HMS Dryad scenarios were a highly complex interaction of crew and communication channels. This chapter describes a study conducted to analyse aspects of command and control in the Naval domain. The operation sequence diagrams give a graphical representation of each of the scenarios with the circles representing transmissions in communication. The anti-air warfare officer was the main agent observed in the air threat scenario and the principal warfare officer was the main agent observed for the subsurface and surface threat scenarios. The knowledge objects identified represent the ideal collection of knowledge objects for the scenarios that were used in the Critical Decision Method analyses. To simplify the analyses, a single network has been presented, comprising both types of knowledge object, but only the knowledge objects relevant to each scenario are highlighted. The knowledge objects pertinent to each phase have been highlighted in each of the propositional networks.
