Choosing Scenarios

• An useability test must have at least one scenario for each item to be tested.
  • Every scenario must address at least one concern, question, or goal of the useability test.

• In deciding which scenarios to write, start by listing the tasks that need to be tested.
  • Then, relate each task to the purpose of the useability test plan.
    • How does this particular task relate to an item listed in the purpose section of the useability test plan?
    • How important is each task for users of the product?
    • How susceptible a particular product element to an useability issue?
  • Choose senarios that rate high on frequency and/or importance.
  • Choose senarios that meet measurable useability objectives.
    • Which tasks should users be able to accomplish easily with few errors? (Efficiency)
    • Which tasks should users be able to finish quickly and efficiently? (Effectiveness)
    • What level of satisfaction should users have after using the product? (Enjoyable)
