A cognition-based classification scheme for design techniques

A cognition-based classification scheme for design techniques is proposed and illustrated here as part of the new Cognition-Based Design (CBD) framework. The classification scheme is based on four components: (1) the stage of the design process in which the technique is applied; (2) the primary cognitive function supported by the technique; (3) the cognitive level required for mastery of the technique; and (4) the cognitive style simulated through the technique. The aim of this classification scheme is to help design students, their instructors, and other design practitioners make better choices about the techniques they use based on the given design opportunity and the desired outcomes, rather than choosing only those techniques with which they are comfortable or those they know best. Recommendations for making use of the new classification scheme in the design classroom are provided, as well as suggestions for future research.
