Task Analysis: The first step is to break down the overall task into discrete steps or stages. Each stage represents a specific activity or action performed by the human operator. Each stage represents a specific activity or action performed by the human operator.
Various models can be created based on the different phases of the CWA. A common way to structure the work domain analysis is to create an abstraction hierarchy, which includes identifying the systems purpose, values, functions, and physical objects. The control task analysis can be analyzed from different perspectives.
