The purpose of Availability Management is to provide a point of focus and management for all availability-related issues, relating to services, components and resources, ensuring that availability targets in all areas are measured and achieved, and that they match or exceed the current and future agreed needs of the business in a cost-effective manner.
Availability Management should take place at two inter-connected levels and aim to continually optimize and proactively improve the availability of IT services and their supporting organization. There are two key aspects:
- reactive activities: monitoring, measuring, analysis and management of
events, incidents and problems involving service unavailability
- proactive activities: proactive planning, design, recommendation and
improvement of availability.
Availability Management activities should consider the availability, reliability, maintainability and serviceability at both service and component level, particularly those supporting Vital Business Functions (VBFs).
The Availability Management process should be based around an Information System (AMIS) that contains all of the measurements and information required to provide the appropriate information to the business on service levels. The AMIS also assists in the production of the Availability Plan.
