Points: 3


IT Resources Availability

Provide the required capacity and performance, taking into account aspects such as normal workloads, contingencies, storage requirements and IT resource life cycles. Provisions such as prioritising tasks, fault-tolerance mechanisms and resource allocation practices should be made. Management should ensure that contingency plans properly address availability, capacity and performance of individual IT resources.

Value Drivers

  • Effective IT resource utilisation
  • Service levels meeting the business requirements
  • Effective IT resource availability management
  Risk Drivers
  • System unavailability due to failing IT resources
  • Inability to predict availability and serviceability of IT services
  • Unexpected outages of IT services

View Control Practices  help

Hide Control Practices  help

  1. Obtain guidance from vendor product manuals to ensure an appropriate level of performance availability for peak processing and workloads.
  2. Identify performance and capacity gaps based on monitoring current and forecasted performance. Use the known availability, continuity and recovery specifications (AI2) to classify IT resources and allow prioritisation.
  3. Define corrective actions, e.g., shifting workload, prioritising tasks or adding system (or other) resources, when performance and capacity issues are identified.
  4. Integrate required corrective actions into the capacity plan, and feed them into the appropriate planning processes (information architecture and technological direction) and change management process.
  5. Define an escalation procedure for swift resolution in case of emergency capacity and performance problems.
