Situation Scenarios and User Centered Design (UCD)

For testing websites or interfaces more generally – mobile phones, remote controls for household equipment – situation scenarios are a rich and efficient technique which Extensia uses regularly.

A dozen interviews are generally sufficient to:

• Assess the overall coherence, graphics and content of an interface,

• Assess the relevance of the functionalities offered,

• Identify stumbling blocks and potential difficulties for users when finding information, navigating or finding their location in the menus.

• Analyse the interface’s strong points, with a view to using them in subsequent developments.

Interviews should not generally exceed 30 to 45 minutes. They are filmed and recorded. The video is used for the analysis. Short video sequences may also be inserted into the study reports, in order to illustrate the results.
