A Service Failure Modes Identifying Method to Realize Highly Reliable Services
Recently, service has been recognized as an effective means to enhance customer satisfaction. The importance of service is widely accepted. According to this background, the authors of this paper have carried out conceptual research on service design from the engineering viewpoint. The series of this research is called “Service Engineering.” In order to achieve a successful service, service providers should maintain the quality of their service and always satisfy their customers. Namely, the provision of highly reliable service is essential for service providers to survive in the target market. In order to realize highly reliable products or services, in general, it is an effective approach to prevent failures from occurring in use phase. In this study, we aim to support service failure analysis in order to minimize the occurrence of failures. This paper proposes a method for identifying the states of service failures. Specifically, we define service failure and propose a procedure to identify the states of service failures with models that are proposed in Service Engineering. The proposed method is verified through its application to a practical case.
