User-centered approach is based on:
“Computer-based systems that are poorly suited to how people actually work impose cost not only on the organisation in terms of low productivity but also on the people who work with them. Studies of work in computer-intensive workplaces have pointed to a host of serious problems that can be caused by job design that is insensitive to the nature of the work being performed, or to the needs of human beings in an automated workplace.”
[Kuhn, S. in Bringing Design to Software, 1996]
Our focus is on formative evaluation
Iterative design & evaluation is a continuous process that examines:
Designers need to check that they understand users’ requirements.
“Iterative design, with its repeating cycle of design and testing, is the only validated methodology in existence that will consistently produce successful results. If you don’t have user-testing as an integral part of your design process you are going to throw buckets of money down the drain.”
