Unknowingly, the relationship between IT departments and their internal customers becomes that of client-supplier based on the mechanisms of marketing and competition. In addition, due to enhanced focus on the customer in the planning, development, and delivery of information service, IT service management(ITSM) has become increasingly important. These days IT management is focusing particularly on the 'de-facto' standard ITIL (IT Infrastructure Library) for implementing ITSM. It is linked as a part of CobiT’s 'deliver and support' domain, which is a framework of IT governance, and ISO/IEC 20000 is a unique international certification standards on the ITSM. This paper proposes the strategy and procedure for ITSM implementation based on ITIL with consideration of IT governance structure for manufacturing industries. It also presents a case study to share the lessons learned and results of an ITSM project.
