STORY TIME

ITIL describes processes, procedures, tasks and checklists that are not

organization-specific, used by an organization for establishing integration

with the organization's strategy, delivering value and maintaining a

minimum level of competency. It allows the organization to establish a

baseline from which it can plan, implement and measure. It is used to

demonstrate compliance and to measure improvement.

• Usually expressed as Percentage

Availability= (AST-DT) X 100 ----------------- AST

AST = Agreed Service TimeDT = Downtime

AVAILABILITY

Availability MetricsMTRS- Mean Time to Restore Service (Down Time) =

Relates to Maintainability (Also has an element of Serviceability)
