Capacity Management

Posted filed under Exin ITIL.

Capacity Management is concerned with ensuring that cost-effective capacity exists at all times which meets or exceeds the agreed needs of the business as established in Service Level Agreements. In ITIL®, capacity is defined as the maximum throughput a service, system, or device can handle.

ITIL®’s treatment of Capacity Management is divided into three major activities:

 

Business Capacity Management (BCM) — addresses capacity factors which exist primarily at the business level such as mergers, acquisitions, plans for new facilities, reductions in force, etc. Typically, BCM factors are addressed first in the overall Capacity Management effort.

Service Capacity Management (SCM)– addresses capacity factors at the service level. Business capacity factors in turn drive Service capacity requirements. The primary task of Service Capacity Management is to translate business capacity factors into capacity requirements for services.

Component Capacity Management (CCM) — addresses capacity factors at the level of components or Configuration Items. The primary task of CCM is to translate Service Capacity Management factors into capacity requirements for individual components or Configuration Items.
