Abstract
To make products have more added values largely from knowledge and services, service engineering is proposing a method for combining products and services at highly level. When customers use products and services, the customer owes not only a monetary cost but also a lot of non-monetary costs: a time loss, a psychological and physical load, etc. Since such non-monetary costs have a great influence when the customers compare several services, service providers need to take into account them. Additionally, service providers, a profit -oriented organization, need to take into account productivity of service to provide. This paper aims at proposing a method to specify unnecessary operation from viewpoints of non-monetary costs and corporate requirements
