Method of measuring and evaluating consumer response for the development of consumer products

A method for evaluating consumer response comprising:

• a. eliciting descriptors of related items from consumers including rational, stereotype and personality descriptors;

• c. eliciting from consumers evaluations of the extent to which the non-eliminated descriptors are attributable to items;
• d. calculating a discrimination index of the evaluated descriptors whereby descriptors, which provide the most discrimination between items and which systematically account for the greatest amount of behavioral variance over 70% among the interviewed consumers, are identified as attributes;
• e. eliciting from consumers identification of uses which consumers associate with items;
• f. eliciting from consumers evaluations of the extent to which attributes are attributable to items for uses associated with the items;

• m. determining for each consumer the propensity of a given change in an attribute evaluation to effect a change in the likelihood of purchasing each item relative to the concomitant change in the likelihood of purchasing each other item whereby a propensity weight is assigned to the attribute evaluations for each consumer which weight corresponds to the slope of the portion of the purchase elasticity curve computed for said consumer falling between the points which represent the items for which the propensity to change is being determined;
• n. calculating a purchase probability for each item by summing the relative proportions computed for each item for all consumers in step l(i);
• o. measuring the change in the purchase probability for each item which results from a given change in an attribute evaluation for all consumers for a given item by (i) calculating for each consumer the concomitant adjustments in other attribute evaluations in proportion to the degree to which said other attribute evaluations respectively correlate to the changed attribute evaluation, (ii) re-valuing these changes and adjustments in proportion to the importance weights and propensity weights, assigned to each attribute evaluation, respectively, and (iii) summing for all consumers the re-valued changes and adjustments associated with each item.
