Abstract

In the development of advanced information systems, emphasis will be on interactive decision making rather than on tools for routine tasks,and there is increasingly a need not only to consider the user-system interface during design but more fundamentally to base integrated systems design on models of proper user-task interaction. In consequence, before ergonomic guidelines are used to judge interface form, the content of user-task interaction should be carefully considered with reference to models of the required cognitive task performance. The basis of cognitive performance, mental models, strategies, information, etc., will vary widely with the work domain. It will, however, for the development of effective tools for the human-machine systems designer be important to seek a generally applicable framework for cognitive task analysis. Within this chapter, a framework is described which characterizes user-task interaction in terms of five model dimensions: the problem domain, the decision task, the role and organization of decision makers (users), mental strategies, and users' cognitive mechanisms and preferences. For each of these dimensions, the modeling concepts are discussed in detail, and the implications are reviewed for a number of application domains such as supervisory process plant control, office systems, CAD/CAM, emergency management, and library systems. Reference is also made to current research within these areas.
