Why delay codes matter
They reveal recurring barriers affecting backlog, schedule compliance, and restoration time.
Delay versus failure cause
A delay code explains why the maintenance process is waiting. It does not describe why the equipment failed.
Common mistake
Using free-text reasons only makes plant-wide analysis difficult.
How this term differs
Maintenance Delay Code is the standardized classification used to analyse why work is waiting. It is related to Work Order Cancellation, Work Order Closure, and Work Order Status, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
