Testing
When conducting Usability Testing, 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. My 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
Inspection
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
Inquiry
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. My Inquiry methods include:
- Field Observation
- Focus Groups
- Interviews
- Logging Actual Use
- Proactive Field Study
