Compose an evaluation plan
To conduct an efficient usability inspection, you need to plan it beforehand. It will give you a sense of control over your work and help foresee inconsistencies. It also lets you discuss the plan with your team. A plan will help you define levels of severity, details of wireframes, what evaluators you want to involve, and other important things.
You might need to have at hand:
- User profile(s)
- Goals
- Scenarios
- Wireframes
- Evaluators
Ultimately, the usability inspection should define the scope — you can't test all functionality at once. Based on user goals, you decide what features and scenarios you want to include in the scope. Then select wireframes that you need for this testing session. Leave out scenarios that are outside the scope at this point.
