A scenario refers to a list of actions users need to perform to complete the task to achieve their goal. And that's how designers usually define scenarios — based on user needs and goals. Teams can also make assumptions about how users navigate the product. Inspection evaluation and user testing methods either prove these assumptions wrong or confirm the hypothesis.

Composing scenarios, ask yourself the following questions:

• Who is going to take the route and complete the task? When answering, make use of the personas.
• What goals do they pursue?
• When do they usually perform this task?
• Where do they perform this task?
• Why do they need to do it?
