Methods

brainstorming
All participants in the design pool ideas; informal, relatively unstructured, but may involve 'on-the-fly' structuring of ideas. All information is recorded without judgement; ideas thus generated can later be filtered

storyboarding
Graphical representationof non-functional system. Can be used to describe the user's day-to-day activities as well as potential designs and their impact.

workshops
Can be used to fill in missing knowledge of both participants and provide focused view of design. May involve mutual enquiry in which both designers and users attempt to understand the context of the design from each other's point of view. May use role play.

pencil and paper exercises
Simple and cheap technique for early assessment of models. Users can 'walk through' typical tasks using paper mock-ups, to show up discrepancies between the users' requirements and the proposed system design
