    Cost evaluation method for service design based on activity based costing
    (Cranfield University Press, 2009-04-01) Kimita, K.; Hara, T.; Shimomura, Y.; Arai, T.; Rajkumar Roy; Essam Shehab
    As our economy matures, customers have begun to demand more services in addition to just industrial products. To address this problem, designers require a novel engineering methodology, called Service Engineering (SE). SE aims to create value by combining services and products. SE focuses more on increasing customer satisfaction, while general service developers need to take into account economic cost in order to be successful in business. This paper proposes a method to evaluate service from the viewpoints of customer importance and economic cost. The proposed method is verified through its application to a practical case.

    A Method of Supporting Conflict Resolution for Designing Services
    (Cranfield University Press, 2009-04-01) Akiyama, Y.; Shimomura, Y.; Arai, T.; Rajkumar Roy; Essam Shehab
    Recently, the importance of service has been emphasized in various industries. However, few studies have focused on service design in spite of its great relevance. This paper proposes a methodology for service design, which enables designers to determine existing conflicts in design solutions and obtain basic strategies to solve them using computers. Two different approaches for detecting conflicts are proposed; one is the use of lexical expressions of functions, and the other involves the ranges of design parameters. At the end, the verification of the proposed methodology is carried out through application to an existing case.

    A Method to Analyze PSS from the Viewpoints of Function, Service Activity, and Product Behavior
    (Cranfield University Press, 2009-04-01) Hara, T.; Arai, T.; Shimomura, Y.; Rajkumar Roy; Essam Shehab
    As our economy matures, combination of tangible products and intangible services becomes a key issue toward a harmonious balance with economic growth and environment conscious. This paper aims to present a method for analyzing structures of service processes described in the modeling method the authors have proposed. It includes three indices of service delivery process according to customer satisfaction elements: (1) visibility to receiver, (2) interactivity with receiver, and (3) degree of receiver participation. Through an application case study, it is found that the method can indicates the features of services, and contributes to acquirement of clues for improving services.

    A Methodology of Persona-centric Service Design
    (Cranfield University Press, 2009-03-31) Hosono, S.; Hasegawa, M.; Hara, T.; Shimomura, Y.; Arai, T.; Rajkumar Roy; Essam Shehab
    In order to clarify the customer’s inclination and provide them with better services, the persona-scenario method has been accepted in Requirements Engineering. A CAD tool proposed in Service Engineering also adopts persona-scenario and focuses on denoting and visualizing the quality factors in service receivers. However, the process of service development with persona has not been fully discussed yet. This paper proposes a methodology to identify the boundary of a whole service system with role and user personas, and formalize the procedure of service development with them. The methodology in service development is exemplified through e-learning services.
