Nowadays Information Technology Services Management (ITSM) has become strongly needed for every kind of organizations providing IT services for customers or for themselves. However, existing models (as CMMI-SVC, ITIL or ISO/IEC 20000) are strongly difficult to implement on very small organizations. The aim of this article is to propose an ITSM model which can be applied in very small organization.
