Course Summary

Generational products that spawn new categories often originate in technical changes that provide new consumer– perceived benefits. Before these benefits can be established, two requirements need to be met. The first is that a change will be perceived by a consumer and the second is that the change will be consumer-relevant. Detecting product changes requires appropriately powered sensory methodology and determining consumer relevance requires a link between sensory testing and measures of consumer response. Inherent in the idea of consumer relevance is that the technical change carries with it a novel benefit often not previously identified by the consumer until they experience the change. Following the articulation of a consumer benefit, research moves into product development and optimization. Finally, the benefit is skillfully articulated in advertising claims that are based on sound advertising claim substantiation with defensible methodology.
