t a single model can be used across multiple domains. 22.6 ITIL Processes Implemented with eTOM Some of the ITIL processes that can be implemented with eTOM are discussed in this section. Service design, service transition, and service operation are three high level ITIL service life cycle processes that can be implemented in eTOM. The sub- processes under these high level ITIL processes can fit into different levels of eTOM model. Let us look into these processes in much more detail. 1. Service design: This process can be further subdivided into the following processes. a. Service catalogue management: This process involves managing the details of all operational services and services that are planned for deploy- ment. Some information from the catalogue is published to customers and used to support sales and delivery of services. Telecom Processes b. Service level management: This process mainly deals with agreements and contracts. It manages service level agreements, operational level agree- ments, and service contracts. Service and operational level agreements are made with the customer who consumes the product and services, and contacts are usually established with suppliers and vendor partners. Capacity management: This process is expected to ensure that the expected service levels are achieved using the available services and infra- structure. It involves managing the capacity of all resources to meet busi- ness requirements. Availability management: This process is expected to plan and improve all aspects of the availability of IT services. For improving availability, first the resource availability is measured. Based on information from measur- ing, an analysis is performed and an appropriate plan of action is defined. e. IT service continuity management: This process is intended to ensure business continuity. It looks into risks that can effect delivery of service and develop plans for mitigating the identified risks. Disaster recovery planning is a key activity performed as part of the IT service conti
