Capacity Management
The aim of Capacity Management is to match the supply of IT resources to customer demands for them. The process is needed to support the optimum and cost-effective provision of IT services by helping organisations to match their IT resources to the demands of the business. It is concerned with having the appropriate IT capacity and with making the best use of it. The demand for IT resources is based on agreeing with users of IT services, levels to which those services will be delivered, based on business requirements and embodied within service level agreements. The customer's needs are assessed by forecasting the likely growth in demand for current services and by sizing new service elements. The desired service levels required can then be agreed with service users, based on business needs. The sub-processes associated with capacity management are concerned with forecasting workload, sizing applications, and maintaining a Capacity Plan in order to meet existing and future needs. The Capacity Plan is beneficial to both Systems Management and Purchasing in order to gain visibility of the schedule and likely infrastructure changes necessary to maintain service at the required levels.
