Capacity Management deals with timely and cost effective preparation of IT capacity due to business demands.
Thus, Capacity Management must support answering the following questions:
- Are the costs of capacity purchasing justifiable in comparison to business requirements? Is the capacity effectively used?
(costs vs. capacity)
- Is the current capacity sufficient to meet current and future customer demand? (demand vs. supply)
- Can the capacity demand peak be effectively met? (Performance Tuning)
- When should additional capacity be purchased and installed?
Capacity Management is divided into three sub processes:
* Business Capacity Management (BCM)
* Service Capacity Management (SCM)
* Resource Capacity Management (RCM).
It is very important that Capacity Management cooperates with other processes from the company and IT strategy fields of business.
