ABSTRACT
A crucial aspect of any modelling enterprise is the quality of the constraints and assumptions within the model. Strategies analysis involves modelling the mental strategies that the agents involved may use during task performance in the domain under analysis. The cybernetic modelling paradigm is concerned principally with the structural aspects of command and control, reducing it to functional entities linked through specific causal pathways according to a deterministic idiom. Agent modelling perspectives appear to represent a form of synthesis between cybernetics and network models. Hierarchical Task Analysis can be viewed, perhaps unconventionally as a form of network model. The work domain analysis involves describing the work environment using an abstraction decomposition space. Social organisation analysis involves identifying exactly how the work is distributed amongst the agents and artefacts within the system under analysis. Worker competencies analysis involves the identification of the competencies that the agents involved are required to possess in order to perform the task(s) in the work domain.
