“Supposing is good, but finding out is better” (Mark Twain)

User-centred design (UCD) is a project-approach that puts the intended users of a site at the centre of its design and development.

It does this by talking directly to users at key points in the project to make sure the site will deliver upon their requirements.

There are four essential activities in a UCD project, as outlined in ISO 13407:

Project stage Description
Requirements gathering Understanding and specifying the context of use
Requirements specification Specifying the user and organisation requirements
Design Producing designs and prototypes
Evaluation Carrying out user-based assessment of the site

The following is a typical top-level characterisation of the most popular UCD methods:

Method Sample size When to use (i.e. project stage)
Focus groups Low Req. gathering
Usability testing Low Design & evaluation
Card sorting High Design
Participatory design Low Design
Questionnaires High Req. gathering & evaluation
Interviews Low Req. gathering & evaluation
