A method for cognitive task analysis is described based on the notion of generic tasks. The method distinguishes three layers of analysis. At the first layer, the task structure, top-level goals of a certain task are identified that have to be fulfilled during task-execution. This task structure may also be viewed as the global strategy to carry out the task. At the second layer of analysis, the local strategies procedures are identified by means of which values are obtained for goals in the task structure. The third layer of analysis consists of a description of the underlying domain knowledge. After a general discussion of the potentialities of the task model in predicting and diagnosing human cognitive behaviour, implications of the model for applied areas such as the development of knowledge-based systems and training, are discussed.
