Although concept evaluation has attracted much attention, collaborative concept evaluation has received minimal attention. In this work, we identify problems and propose solutions regarding collaborative concept evaluation. First, we reviewed past projects and interviewed evaluators with international design experiences to conclude that concept evaluation criteria are not established but constructed. Second, we apply the psychology of Brunswik’s Lens model to propose that providing multiple concept aspects improve collaborative concept evaluation. Three experimental studies demonstrate that our proposed Concept Aspect Profile (CAP) model (1) is superior to existing concept evaluation models, (2) differentiates between breakthrough new product concepts and incremental new product concepts, and (3) increases the likelihood that a concept receives the Industrial Design Excellence Award (IDEA). This work contributes to marketing research of concept evaluation as well as provides implication for designers.
