A goal that must be accomplished in service of a higher-level goal. Goals are often expressed as a hierarchy of goals and several levels of subgoals. The lowest level of subgoals are accomplished through operators, which are decomposed no further.
See state transition network.
A way of analyzing work that focuses on different ways that a particular control task might be carried out. An analytic phase of cognitive work analysis.
A collection of informal and formal analysis techniques that focus on the differences and relationships among discrete event phenomena (e.g., a key press, a project deadline) and more continuous status phenomena (e.g., the current mouse position, the weather, the current screen display) See:http://www.hcibook.com/alan/topics/status/

A representation of dynamic systems including states (usually as labeled circles or boxes) and arcs labeled by actions that form transitions between the states.
In computing, this usually refers to the inner memory of a computer at a particular point of time, but more generally it is that in the present that encapsulates all that of the past that can effect things in the future.
This is a computational process that determines activation values over a set of interassociated cognitive structures. The spread of activation from one cognitive structure to another is determined by weighting values on associations among chunks. Activation values indicate degree of relevance to ongoing cognitive processes.
socio-organizational Church-Turing hypothesis
The recognition that organizations perform, among other things an information-processing role, and the supposition that this means we are likely to see similar structural elements and processes in the physical and social aspects of the organizations as we do in electronic computers.
