We introduced a variation of Consensus Assessment Technique(CAT) to measure creativity in highly professional products in business settings. We introduced multiple facets such as raters and creativity dimensions, and multiple criteria such as novelty, resolution, and elaboration/synthesis in creativity measurement of professional flower designs. Generalizability theory was employed to implement and assess this complicated measurement design. From results of application to flower designs, we discuss two issues: Professionals are appropriate, whereas lay people are not as judges for professional products. Professionals are very consistent in rating the product creativity in their field. Relying on lay people when measuring creativity in professional products would not produce a desirable level of reliability. We, however, feel optimistic of acquiring a desirable level of reliability with a reasonable number of raters and dimensions. This approach of investigating optimal conditions for measurement would bea very useful guide for measuring creativity in business settings.
