ITIL Capacity Management

The IT Infrastructure Library (ITIL) has gained widespread acceptance in the IT community in the years since its inception by the CCTA in the late 1980s and is now the foundation of the BS15000 standard. The core of ITIL is Service Management, which divides into two logical groups of processes: Service Delivery and Service Support. The Service Delivery core area comprises the following processes:

• Capacity Management
• Service Level Management
• Financial Management for IT
• IT Service Continuity Management
• Availability Management

While Capacitas focuses on the process that ITIL defines as Capacity Management, we do not believe that the other four processes are able to function effectively without the Capacity Management process. As such, we offer a range of services to provide an effective Capacity Management process, as defined by ITIL, creating the foundation for the other Service Delivery processes.

The key features of ITIL Capacity Management are:

1. Service Alignments:
   • Business Capacity Management - relating the business demand requirements and expectations to the available supply of resources
   • Service Capacity Management - relating individual ICT services and their service level requirements to the appropriate resources, thereby determining the resources needed
   • Resource Capacity Management - ensuring that each resource platform has sufficient capacity to support all the required services on that platform

2. Activities:
   • Demand Management - ensuring that customer demand is matched to available resources in an optimal fashion
   • Modelling - providing mathematical-based software models to predict the required resource usage for a given input demand or at a particular moment in time
   • Application Sizing - predictive forecasting of resource requirements for a new or changed application
   • Storage of capacity management - data design and build of a central repository for capacity and performance data, known as the Capacity Database (CDB)
   • Production of the Capacity Plan - the authoring and delivery of a predictive plan for what capacity options may be required of each type, when, and how much it will cost
