Abstract
Due to the improvement of the Internet use environment including the mobile network, diversification and high functionality of the terminals, anyone can use a great variety of IT services anytime, anywhere. The method of offering IT services to the user diversifies. In some cases, the target service is offered directly, but in another cases, the target service is offered as option service or is offered by the collaboration with a competitor or the different type of industries. In such situations, it is necessary for the service providers to continuously enhance the service strategy to maintain and increase the market share between competing services by considering a change of the whole market and the customer expects. Therefore, the decision making about development, introduction, an evaluation, improvement and the marketing strategy of IT service is becoming a very important problem for service providers. We propose the IT service management platform to support the problems about decision making.
