Analysing creative behaviour in the later stage design process

• We develop a framework for analysis of late stage engineering creative behaviour.
• We present the usefulness, validity and reliability of the analysis method.
• Variation in behaviour of designers throughout the design process is demonstrated.
• Two different approaches to creative behaviour in later stage design are identified.
• More effective methods of supporting designers in later stages can be developed.

Creativity is widely seen as an important subject in the study of the engineering design process. This paper presents a framework and coding scheme for the analysis of creative designer behaviour within the later stage engineering design process, validated through a longitudinal study. By classifying the tasks that designers complete throughout the design process, analysis has demonstrated two different approaches to creative behaviour in later stage design; dependent on the way in which designers identify, develop and use knowledge and design variables. Through such analysis, the understanding required to develop specific and particularly appropriate methods of designer support can be gained, dependent on the stage of the design process and particular approach of the designer.
