There are generally three types of usability evaluation methods: Testing, Inspection, and Inquiry.
In Usability Testing approach, representative users work on typical tasks using the system (or the prototype) and the evaluators use the results to see how the user
interface supports the users to do their tasks. Testing methods include the following:
- Coaching Method
- Co-discovery Learning
- Performance Measurement
- Question-asking Protocol
- Remote Testing
- Retrospective Testing
- Shadowing Method
- Teaching Method
- Thinking Aloud Protocol
In Usability Inspection approach, usability specialists -- and sometimes software developers, users and other professionals -- examine usability-related aspects of a user interface. Commonly used Inspection methods are:
- Cognitive Walkthroughs
- Feature Inspection
- Heuristic Evaluation
- Pluralistic Walkthrough
- Perspective-based Inspection
Here, usability evaluators obtain information about users' likes, dislikes, needs, and understanding of the system by talking to them, observing them using the system in real work (not for the purpose of usability testing), or letting them answer questions verbally or in written form. Inquiry methods include:
