Traditional user-centered methods don't really address the design issue,
but assume that the screen design somehow pops out of the air. The user-centered
methods deal with how to find the usability problems in the design. The
designer then has to correct the screens, test again, and so on. This approach
corresponds to writing programs without plan and structure, and then test
and correct them until they work. This trial and error approach has long
been abandoned in software engineering, but what is the solution for the
I will show a systematic design approach we have been using for several years by now. It starts with two traditional descriptions: a data model and high-level use cases (task descriptions). From that you design the screens in a systematic way. The result is better task support than traditional approaches, a system that is easier to understand, and fewer screens in total. As with good programming, the result is not error free, but it has only minor problems that are easy to correct.
