What usually happens when IT talks capacity planning to the business? Eyes roll, interest drops, and the c-suite changes the subject. Some of the problem is due to a language barrier. Think response time versus utilization. Another issue is capacity planning has no value in the eyes of its beholder - your business customers. HSBC head of capacity planning Tim Collins suggests a few “hidden value adds” that IT can use to show immediate value from capacity planning activities. They’re even listed in a way to catch the attention of your business customers.
Proactive analysis of performance data can help identify issues such as filling file systems, memory leaks, and looping processes. If these can be done far enough in advance (e.g., 14 days+), then the issue can be fixed with a planned change, rather than reactive support.
The capacity planning team can identify where existing capacity is available on already provisioned hardware if they are involved in solution design and hardware provisioning. This can save considerable costs on both hardware and software.
Reduced software costs
Capacity Planning would be in the ideal position to advise when platforms need to be updated, and can calculate the optimum layout of virtual servers. This can save proprietary software costs (e.g. RDBMS, WebSphere, etc.), and also reduce/eliminate the need for extended support on existing hardware platforms. In addition, direct savings on COTS package cost by reducing the number of servers / CPUs in the environment would be available.
