Requirements definition, Use Cases

Analyizing Focus Group Findings

Draft a list of findings from the Contextual Inquiry (and later from the Focus Groups) in terms of needs, whishes, ideas which have been articulated.

Check for consistency. Are there any contradicting needs or whishes, any controversies?

Set priorities according to your own judgement.

Requirements Collection

Describe requirements based on findings from CI, (focus group), and your own intelligent common sense.

Collect requirements in a list.

Relate them to the source, and - where possible and appropriate - to personas and scenarios.

Use Cases

Based on priorities in the findings list above, select and describe use cases, that catch the important functions you want to work on in the future. Describe a small number of use cases which together might represent a usage scenario.

You might also want to update personas and scenarios if needed.

The list of requirements and the collection of use cases will be updated after the focus groups.

After this, work will continue on storyboards (and prototypes).
