• Requirements – what is wanted

  • The first stage is establishing what exactly is needed
• Analysis

  • The results of observation and interview need to be ordered in

  some way to bring out key issues and communicate with later

  stages of design.
• Design

  • It is at this stage also where input from theoretical work is most

  helpful, including cognitive models, organizational issues and

  understanding communication
• • Iteration and prototyping

  • Some forms of evaluation can be done using the design on paper,

  but it is hard to get real feedback without trying it out. Most user

  interface design therefore involves some form of prototyping,

  producing early versions of systems to try out with real users.
• Implementation and deployment

  • Finally, when we are happy with our design, we need to create it

  and deploy it. This will involve writing code, perhaps making

  hardware, writing documentation and manuals – everything that

  goes into a real system that can be given to others.
• • Over time many people are affected directly or

  indirectly by a system and these people are

  called stakeholders.
• Talk to them. => participatory design

  (involving users throughout the design process it is possible

  to get a deep knowledge of their work context and needs.)
• Watch them.

  ▪ The observations tell you what they do, they will tell you

  why.
• Use your imagination. One method that has been quite

  successful in helping design teams produce user focused

  designs is the persona. A persona is a rich picture of an

  imaginary person who represents your core user group
