support network inventory

It then passes to the production phase. This phase concentrates on the operation of the service. It begins with an update of existing inventories (this part is often tied to the actual deployment), followed by a process for change tracking for the service. Since the service is deployed, it will require both problem management and user support network inventory in addition to the administration of service availability. This is done through regular backups and data protection as well as security verifications and service maintenance. If data is associated with the service, storage management will also be involved. Service operation also entails service level agreement maintenance. This is done through performance tuning, capacity adjustments, and the generation of statistics on availability, reliability and responsiveness of the service.

Finally, once the service has exhausted its value to the business (its operation costs outweigh the benefits it brings), it must be retired and replaced. This is done through managed obsolescence—the verification of the continued usefulness of a product or service within the network. When it has been determined that retirement is required, you proceed to the removal of the service from the network and the process begins all over again with a replacement service.
