MAINTAIN
Maintain for reliability.
Plant maintenance
The work, against the model. Every inspection, test and record lands on the part it belongs to.

A value in square brackets is a placeholder. The record stays on the part whoever opens it.
How it works
Three things, in this order.
01
The record, on the part
Inspection data, schematics, CAD, manuals and test records sit on the equipment they describe, found from the part rather than from a folder.
02
Validated first
The twin is checked before it is trusted. Once validated, commissioning, testing and inspection work against it: what was checked, on which part, by which document.
03
One history
The work done and the alarms raised sit side by side on the same part, so the next person starts from what happened last, not from a tag name.
