Scenarios

A set of techniques used before the product exists to define the use of a future system.

Narrative description (story) of the envisioned use.

Not looking at it from the perspective of the solution but how people interact with the system.

Scenario Based Design

Should be done at the beginning to avoid costs of wrong/bad design.

Why:

• develop further alternatives
• raise questions about assumptions behind the scenarios.
• analyse software requirements
• specifications of functionality
• guide ui layouts and ui control
• rapid communication.
