Design Theory and Methodology in HCI: Applying CPM/PDD to UCD

The development of human computer interfaces is a complex, multifaceted process with many soft influencing factors and boundary conditions. In addition to other approaches, the user-centered design has proved to be a meaningful and suitable model to support the development of interactive systems. Also, in design theory and methodology, a research field that investigates similar processes for the area of mechanical engineering, a large number of models have been investigated. This paper applies the Characteristics-Properties Modelling/Property-Driven Development (CPM/PDD) to User Centered Design (UCD). It explores the mapping of the two models to obtain support and insights for the selection of techniques and metrics for the development of interactive systems. For this purpose, this paper first describes CPM/PDD and discusses why it is particularly suitable for the considerations made here. After a short description of the UCD, the paper explores touch points and maps the two models to each other. A small case study shows the possible application and offers a starting point for further research.
