CobiT definition:
The need to manage performance and capacity of IT resources requires a process to periodically review current performance and capacity of IT resources. This process includes forecasting future needs based on workload, storage and contingency requirements. This process provides assurance that information resources supporting business requirements are continually available.
Control over the IT process of
Manage performance and capacity
that satisfies the business requirement for IT of
optimising the performance of IT infrastructure, resources and capabilities in response to business needs
by focusing on
meeting response time requirements of SLAs, minimising downtime, and making continuous IT performance and capacity improvements through monitoring and measurement
is achieved by
- Planning and providing system capacity and availability
- Monitoring and reporting system performance
- Modelling and forecasting system performance
and is measured by
- Number of hours lost per user per month due to insufficient capacity planning
- Percent of peaks where target utilisation is exceeded
- Percent of response-time SLAs not met
Control objectives:
DS3 Manage Performance and Capacity
