Scope and terms of reference of the plan
Ideally, the Capacity Plan should encompass all IT resources. This section should explicitly name those elements of the IT infrastructure that are included and those that are excluded, if any
The Capacity Plan uses information gathered by the sub-processes. This sub-section, therefore, should contain details of how and when this information was obtained – for example, business forecasts obtained from business plans, workload forecasts obtained from customers, service level forecasts obtained by the use of modelling tools
It is important that any assumptions made, particularly those concerning the business drivers for IT Capacity, are highlighted early on in the plan. If they are the cornerstones on which more detailed calculations are built, then it is vital that all concerned understand this
The service summary section should include:
The resource summary section should include:
Options for service improvement
Building on the results of the previous section, this section outlines the possible options for improving the effectiveness and efficiency of Service Delivery. It could contain options for merging different services on a single processor, upgrading the network to take advantage of technological advances, tuning the use of resource or service performance, rewriting legacy systems, purchasing new hardware or software etc.
The costs associated with these options should be documented here. In addition, the current and forecasted cost of providing IT services should be included. In practice, Capacity Management obtains much of this information from the Financial Management process and the IT Financial Plan.
The final section of the plan should contain a summary of the recommendations made in the previous plan and their status – for example, rejected, planned, implemented – and any variances from the plan. Any new recommendations should be made here, i.e. which of the options mentioned in the plan is preferred, and the implications if the plan and its recommendations are not implemented should also be included.
The recommendations should be quantified in terms of the:
