  1. CTA Data Collection • Interviews • Unstructured • Semi-Structured • Structured • Accident reports • Observation • Think-aloud protocol • Communications • Domain documents • Domain artifacts • Literature review • Logic-based decomposition (i.e., no data)

  2. Cognitive Work Analysis Cognitive Domain Analysis to produce an Abstraction Hierarchy which should support Ecological Interface Design Rasmussen & Vicente

  3. 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

  4. Abstraction Hierarchy

  5. Abstraction-Decomposition Analysis Levels of Decomposition  Levels of Abstraction 

  6. Abstraction-Decomposition AnalysisRasmussen, Pjtersen, and Schmidt, 1990

  7. Abstraction-Decomposition AnalysisRasmussen, Pjtersen, and Schmidt, 1990 The descriptions in each cell can become the categories used to code your data
