The documentation-to-floor gap: the most common QMS failure nobody names

Every ISO-certified manufacturer has a gap between what the documented QMS says and what operators actually do on the floor. The gap exists because procedures are authored at one point in time, the operation evolves continuously, and internal auditors are too close to the operation to see the deviations they have already accepted. Registrars find this gap in twenty minutes during surveillance because they are trained to follow one work order through the floor and compare what they observe to what the documentation describes. Closing it requires either a documentation refresh, a floor-practice refresh, or both, depending on which side is wrong.
