Cognitive walkthroughs are performed at any stage of design using a prototype. This approach is intended especially to help understand the usability of a system for first-time users, that is, for users in an exploratory learning mode.
A cognitive walkthrough starts with a task analysis that specifies the sequence of steps or actions required by a user to accomplish a task, and the system responses to those actions. The designers and developers of the software then walkthrough the steps as a group, asking themselves a set of questions at each step.
Data is gathered during the walkthrough, and afterwards a report of potential issues is compiled. Finally the software is redesigned to address the issues identified.
I will blog our task analysis and then each of our personas can carry out a cognitive walkthrough.
