A Method-Independent Process Model of User-Centred Design

Abstract

We propose a method-independent process model of user-centred design (UCD). It is based on recognised sources and its structure was developed in a set of assessments in industrial settings. The result is a process model that identifies six main processes of UCD. Each of these is defined through a set of outcomes. The model makes tangible the interface between the usability engineering and design processes. The model has provided a practical basis for the assessment of UCD processes, which was the original scope of the model. In addition, we have found the model as a useful asset in training UCD and in planning UCD activities in projects.
