A novel integration of human factors methods to analyse C4i activity: a chemical incident case study carried out with the UK fire service

This paper presents an integration of seven human factors techniques into a comprehensive task and knowledge based methodology. The case study demonstrates that the proposed methodology can be successfully applied to the analysis of command and control (C4) teams and shows how each of the methods interface with each other to produce; a process based overview using an enhanced form of Operation Sequence Diagram (OSD∗), and a knowledge based overview using a Propositional Network. This paper demonstrates how the methodology enables key constructs within C4 domains to be captured for the purpose of designing future systems
