Cognitive Work Analysis Cognitive Domain Analysis to produce an Abstraction Hierarchy which should support Ecological Interface Design Rasmussen & Vicente
CWA Goals • Design interfaces that help control system operators manage unexpected system upsets • Define system in terms of constraints that shape system functioning and guide operator responses. • System purpose, natural laws, policies, functions, equipment, etc. • Support Visibility • “optimal control requires a consideration of veridical system functioning” • Support Operator Mental Model
