User-centered 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 the user at key points in the project to make sure the site will deliver upon their requirements.

The stages are carried out in an iterative fashion, with the cycle being repeated until the project's usability objectives have been attained. This makes it critical that the participants in these methods accurately reflect the profile of your actual users.

ISO 13407 outlines four essential activities in a user-centered design project:

• Requirements gathering - Understanding and specifying the context of use
• Requirements specification - Specifying the user and organisational 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 user-centered design methods:

Method	Cost	Output	Sample size	When to use
Focus groups	Low	Non-statistical	Low	Requirements gathering
Usability testing	High	Statistical & non-statistical	Low	Design & evaluation
Card Sorting	High	Statistical	High	Design
Participatory design	Low	Non-statistical	Low	Design
Questionnaires	Low	Statistical	High	Requirements gathering & evaluation
Interviews	High	Non-statistical	Low	Requirements gathering & evaluation
