A Method for Service Function Improvement Starting From the Service Delivery Process
In the manufacturing sector, product-service systems (PSSs) have attracted considerable attention as a means to unify and integrate the design of products and services. In order to maximize customer value, the design of products and services should be integrated. Thus far, unified schemes related to service activities and product behaviors have been proposed in the field of service engineering. In these approaches, services are modeled from the viewpoint of function, and a service delivery process that is based on service activities and product behaviors is developed. However, when service providers attempt to improve their service, the existing PSS methods are inadequate from the viewpoint of providing suggestions for improvement. Therefore, this research aims to establish a method for PSSs to suggest improvements in their own service. Thus, in this paper, the authors propose a method for service function improvement that involves analysis of the service delivery process and enhances customer value.
