Abstract
This paper provides experimental verification that a service’s vision can be expressed by iterations of "prior image construction of the Ba based on the purpose" and "structuring by coordination between viewpoints". Services can be drawn as visuals models using an idea sketch sheet to express purposes and contexts that are difficult to verbalize. The service modeling sheet also facilitates the iterative design of the business-service-product hierarchy. Testing confirmed that a service’s vision can be visually modeled by anyone regardless of their professional background or design skills. Based on these results, the vision building process models the service in terms of both concept and images, and identifies the products needed to enable the service by recognizing and correcting their mismatching elements or anomalous structure. In addition, since the modeled vision can be shared with others, a wide gamut of interpretations can be fostered among the participants.
