Operator source match
The converted result is checked directly against the original for missing or misread content.
Quality control
Three checks between conversion and delivery.
The original three-level quality-control approach is retained and clarified: operator source match, project plot review and senior final validation.
Project / plot review
The project reviewer checks plots, alignment, naming, coordinates, curve identity and output rules.
Senior final validation
Corrections are confirmed and the complete delivery package is reviewed before release.
