Capacity Planning is the "establishment of a regime where computing resources are supplied as necessary for the consistent provision of a required service at a known and controlled cost". It is conerned with both business issues and technical detail. It is about:
• Effective Planning
• Business Decisions
• Service Levels
• Workload Prediction
• Analytical Modeling
Effective planning means producing plans which allow business decisions to be backed up by the right quality of computer support to users. This process involves predicting the workloads which will result from new and changed business directions, and using analytic models to determine the future performance of IT.
The solution lies in establishing and maintaining a well controlled and timely procurement plan to the benefit of the enterprise. The alternative is the problem of trying to resolve performance panics and shorten procurement cycles.
