Q

Multidisciplinary team

A

a group of individuals which have different jobs that work together

23
Q

Principles of UCD

A
  • design is based upon understanding of users, tasks and environments
  • users are involved throughout
  • design and development
    design is driven and refined by user-centered evaluation
  • process is iterative
