What is Usability Testing?
- Usability testing involves creating user profiles and breaking users into clear subgroups.

- Ideally, users from all major profiles are tested, but if limited, profiles are chosen based on the highest number of users or those that may have the greatest usability issues.
Step 1: Create User Profiles and Choose Participants
- Create user profiles by breaking users into clear subgroups.
- Define the characteristics of each subgroup.
- Choose user profiles to test based on highest number of users or potential usability issues.
Step 2: Decide What to Test
- Determine the order of tasks: start with easy tasks, follow a sequential order, or be random.
- Create written test materials, including:
- Task list for users
- Written welcome speech/intro
- Consent forms
- Observation forms
- Pre-task and post-task questionnaires and interview questions
Step 3: Prepare for the Test
- Recruit participants and determine "payment" or incentives.
- Define team member roles, including:
- Facilitator/Briefer
- Observation recorder/note taker
- Camera operator (optional)
- Help desk operator (optional)
- Test administrator (optional)
- Emphasize that the test is not evaluating the user, but the product.
