ITIL® Capacity Management Realizing the Importance of Cost Effective Project Implementation The ITIL® Capacity Management process ensures that provision of IT services is at its optimum and cost effective level by helping IT companies match their available resources to the demands of the business. It is a key element for proactive engineering of IT services, making sure that certain IT resources and infrastructure can be utilized or are made available should the need arises. Capacity Management activities include the following:
(1) Monitoring and modeling to simulate the performance of IT services and its supporting components and understand future resource needs. (2) Analyzing, tuning, and implementing necessary activities to make efficient uses and changes in resource utilization. (3) Managing and understanding the current demands for computing resources and deriving forecasts for future requirements, which involves an understanding of business priorities. (4) Application sizing to ensure required service levels can be met. (5) Building the yearly infrastructure growth plan with inputs from other team members. (6) Storing capacity management data while predicting the IT resources needed to achieve agreed service levels. (7) Producing a capacity plan that documents current utilization and forecasted requirements, as well as support costs for new applications or releases.
In addition, one of the main reasons why ITIL® Capacity Management should be implemented first is that it offers fast and early wins that will often produce enough cost savings to finance the remainder of the ITIL® project. Demonstrating success and recovering implementation costs early on also helps encourage the management to stay intact and gain momentum for the project while easing out organizational resistance. These certain advantages make ITIL® Capacity Management a good candidate for a pilot implementation of the project.
