KPI for restoration speed

MTTR – (MDTR)

Mean Time To Restoration – (Mean Downtime To Restoration)

MTTR describes the time from fault detection to restoration of the machine. It may include administrative and logistics delays.
Example: during a month, the maintenance department spent one hour fixing a pump the first time, two hours the second time and three hours the last time. MTTR for this pump is two hours.

MWT

Mean Waiting Time

Mean Waiting Time describes the time it takes for a fault (not planned jobs) to be registered and maintenance technicians starting to work on the problem. In order for this KPI to be measurable, it has to be clearly defined what it means to start working on a task.
Example: A corrective maintenance task takes 8 hours to complete. It took 4 hours for the spare part to arrive until the team could start working. MWT is at least 4 hours.

Downtime due to missing spare parts

Hours of downtime caused by missing spare parts
