Capacity Management is perhaps one of the easiest processes to cost-justify. The benefits of CM in both financial and service terms will typically far outweigh infrastructure costs. Experience of introducing ITIL® CM into large organizations indicates that over the first few years of introduction there is likely to be an average net saving of the order of 10% on capital expenditure and operating costs.
A last minute Capacity Planning exercise identified a £100,000 option from which the user got the same performance as they would have got for the £1m expenditure they were about to make on a vendors recommendation before the planning study. Another site saved the entire costs of establishing a new Performance Assurance function in its first study.
