Abstract
Although the designer has been recognized to have a particularly important role in product development, design method development still shows a lack of putting the designer in the focus. This contribution presents an approach to develop designer-centred methods in three steps: Assessment of designer thinking, design method synthesis and design method validation. To illustrate the approach, the development of a design method to overcome cognitive bias in product development is presented using the approach. Cognitive biases are systematic deviations from rational decisions that lead to illogical interpretations of information or data. By taking cognitive bias and designer thinking into consideration, data driven design can be better supported. The method development here addresses the confirmation bias, a particularly difficult bias. With the Design-ACH, a method is presented that supports design engineers in reducing the confirmation bias, which is shown by results of multiple studies. Implications for future development of designer-centred methods include data driven method development, which can be made possible by automated quantitative measurement of designer thinking. Also, there is a need for studies in both laboratory and field to ensure designer-centred method development.
