  1. Scenarios (defn):
    Scenarios specify how users carry out their tasks in a specified  context.
  2. Benefits of scenarios or use cases:
    • 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
    • Can  help identify usability targets and likely task completion times
    • Promotes developer buy-in and encourages a user-centred design approach.
    • Can also be used to generate contexts for evaluation studies.
    • The technique can be used by developers with little or no human factors expertise.
  3. Method of scenarios
    • Gather the team
    • Identify intended users, their tasks and the general context --provide the basis for the scenarios
    • Functionally decompose user goals into the operations needed to achieve them.
    • Consider which activities should be performed by the user and which by the computer.
    • Create an outline of the users' activities, goals and motivations for using the system being designed, and the tasks they will perform.
    • To maintain design flexibility, scenarios should not specify what product features are used.
    • Assign task time estimates and completion criteria as usability targets.
    • The session can be videotaped for later review or transcribed for wider distribution.
    • The results from scenario building sessions can be used to plan user-based evaluations.
  4. Try to generate scenarios to cover a ___  ____ of situations, not just the most ___ ___ or those of most interest to the ____ ___.
    Try to generate scenarios to cover a wide range of situations, not just the most common ones or those of most interest to the design team.
  5. Try to include ___ ____ that will test the ___ ___, not just ___ ___ scenarios.
    Try to include problem situations that will test the system concept, not just straight forward scenarios.
  6. Work through the scenarios ___ and ___ __ ___ on that basis rather than trying to ___ __ _____ half way through
    Work through the scenarios fully and judge the system on that basis rather than trying to change the system half way through
