Reliability & Operations

Translate an availability percentage into a downtime allowance for a chosen period.

Estimate availability for independent serial dependencies or parallel alternatives.

Calculate average operating time between failures and average repair time.

Check whether estimated recovery time and backup frequency meet recovery targets.

Check whether planned work and rollback fit inside a maintenance window.

Sort timestamped incident events and show elapsed minutes from the first event.

Build a structured handover covering incidents, changes, risks and runbooks.

Compare downtime allowances for several availability targets.
