Top Highlights

• There are four techniques in ACTA, and all of them are pretty straightforward to put to practice: You start by creating a task diagram.
• You do a knowledge audit. A knowledge audit is an interview that identifies all the ways in which expertise is used in a domain, and provides examples based on actual experience.
• You do a simulation interview. The simulation interview allows you to better understand an expert’s cognitive processes within the context of an single incident
• You create a cognitive demands table. After conducting ACTA interviews with multiple experts, you create something called a ‘cognitive demands table’ which synthesises all that you’ve uncovered in the previous three steps
• The goal when creating a task diagram is to set up the knowledge audit and the simulation interview
