Try to include problem situations that will test the system concept, not just straightforward scenarios. Work through the scenarios fully and judge the system on that basis rather than trying to change the system half way through. More information Scenarios are most useful when produced early in development as specific realistic and detailed examples of what a user would do, but without making any reference what user interface features that would be used. See the examples . Scenarios can also be used later to explore how the interface would be operated.
Next steps Use the scenarios as a basis for developing more specific usability requirements .
