Projects/Usability/HIG/Scenario

Purpose

A scenario describes the whys and wherefores a persona makes use of the application. It illustrates how the user achieves their goals by means of a task-orientated example. In contrast to use cases known from requirements engineering a scenario is more descriptive. It is supplementary to a persona, providing together an efficient method applicable in a wide range of applications.

Guidelines

• Always create scenarios based on empirical data.
• Take technical configuration, environmental condition, organizational and social aspects into consideration.
• If available, use real world images to support imagination.
• Try to include problem situations that will test the system concept, not just straightforward scenarios.
