:Purpose
To provide examples of usage as an input to design, and to provide a basis for subsequent usability testing. Scenarios specify how users carry out their tasks in a specified context. To maintain design flexibility, they should not specify what product features are used.
:Benefits
•It encourages designers to consider the characteristics of the intended users, their tasks and their environment.
•Usability issues can be explored at a very early stage in the design process (before a commitment to code has been made).
•Scenarios can help identify usability targets and likely task completion times.
•The method promotes developer buy-in and encourages a user-centred design approach.
•Scenarios can also be used to generate contexts for evaluation studies.
•Only minimal resources are required to generate scenarios.
•The technique can be used by developers with little or no human factors expertise.
:Method
An experienced moderator is recommended for the sessions in which the scenario is explored.
