Service CAD system to integrate product and human activity for total value

Good combination of product and service is a key issue to balance economic growth with environmental concerns. This paper aims at demonstrating a design method to integrate products and service activities for total value. Our design method differs from Traditional Engineering and Concurrent Engineering in that products and service activities are designed in parallel according to customer value. To establish such design method, the service blueprinting method from marketing field, which describes service delivery processes, is extended to include product and its behavior. Function structure of service for the receiver state works as a bridge between product behavior and service activity. Both the above method and the CAD tool are demonstrated through an example presented herein.
