Temporal Coordination Control Task Analysis for Analysing Human-System Integration

Evaluating whether prospective air defense systems will effectively integrate the activities of humans and computers is a pressing issue for developers and purchasers of such systems. We need effective ways of modeling human-system integration while such systems are under development and while the possibilities for action are underspecified. We present a Cognitive Work Analysis-based analytic framework under development for characterising air defense control tasks and also for characterising the larger framework in which such control tasks must be coordinated. The challenge is to produce a formative rather than descriptive or normative model, within which broad logical and temporal constraints can be represented, so revealing possibilities for action as events unfold.
