In order for any business organization to perform on a successful level, it is necessary that it has a defined set of activities that manage IT processes and services. Defined set of activities constitutes the Service Management of that organization. There are many types of Service Management, and this paper is based on the type of which is called Information Technology Infrastracture Library V3 (ITIL V3). ITIL V3 has a total of five phases: Strategy Service, Service Design, Service Transition, Service Operation and Continual Service Improvement. This paper is focused on the description of its second phase, which is called Service Design. The aim of this paper is to describe information systems development of the Telecom Operator for Service Design phase of the ITIL v3 methodology in all seven of the processes that are contained in these phases. These are: Service Catalogue Management, Service Level Management, Capacity Management, Availability Management, IT Service Continuity Management, Information Security Management and Supplier Management. This paper attempts to show to the telecom operators that during the realization of their IT processes they do not necessarily have to use the eTOM standard, but may use other standards and concretely they can use ITIL V3 standard. This paper in its conclusion, with previously detailed analysis of the implementation of the Service Design processes according to ITIL V3 methodology in the information system of the telecom operator, needs to define which teams are required to implement the Service Design processes and which are the activities that each team has during the implementation of the information system of the telecom operators.
