10: Update Forecasts and Utilizations
The process of capacity planning is not a one-shot event but rather an ongoing activity. Its maximum benefit is derived from continually updating the plan and keeping it current. The plan should be updated at least once per year. Shops that use this methodology best update their plans every quarter. (Note that the production acceptance process also uses a form of capacity planning when determining resource requirements for new applications.)
These 10 cardinal rules will go a long way toward formalizing the capacity planning process for an infrastructure, and should help ensure that adequate computer and network resource capacity is always available. This can result in capacity planning becoming one of the first infrastructure processes to be implemented, rather than the last.
