The downtime record
Unplanned stops by cause, so that repeats become visible — because a repeated cause is a design problem rather than a maintenance one.
The deliverable
What it is
Downtime recorded only as hours lost tells you the size of the problem and nothing about what to do. Recorded by cause, the same data usually points at a handful of specific items.
A cause that recurs is not a maintenance failure. It is a design, specification or operating problem that maintenance keeps repairing.

The causes
Why each stop happened, in categories that can be counted.

Short frequent stops go unrecorded and collectively exceed the large ones. Set the recording threshold low.
The other components in maintenance
The maintenance regime
Which approach applies to which asset — preventive, condition-based or run-to-failure — chosen on consequence rather than habit.
LearnThe schedule
Planned work with protected windows — because a window that is always surrendered to production is not a schedule.
