Cognition and the engineering design requirement
This thesis is concerned with the engineering design requirement and the process by which it is elicited, evolved and recorded. The purpose of the research reported in the work is to achieve a more complete understanding of the engineering design requirement, and to apply that understanding to the better support of designers during the design requirement capture phases of the design process. Two perspectives dominate the approach to the research. The first concerns the relation between the design process and human cognition. The research subject is seen as being fundamentally a product of the human mind and that such things as knowledge, language and meaning – the things commonly associated with cognition – are crucial to its proper understanding. The second perspective is informed by the view that the development of the design requirement can be seen as a knowledge-intensive process of communication. Thus, understanding communication between humans and some aspects of communication failure can assist in understanding and remedying failure in design requirement capture.
