The drawing changed after programming: close the old version first
A revision procedure should identify affected parts, programs and work already in progress.
A revision procedure should identify affected parts, programs and work already in progress.
A revised drawing is easy to email and harder to carry consistently through production. The important question is what has already happened under the previous revision. A shop needs a way to establish that state before a replacement file is treated as the new instruction.
Identify the affected work
Record the job, old revision, new revision and a plain description of the change. Have the responsible production person determine which programs and parts are affected. Include work already cut, parts waiting at another station and items prepared for dispatch. Do not assume that replacing a file in one folder updates those physical stages.
The programmer should make the technical changes through the approved process. The coordinator’s role is to track who has acknowledged the revision and when the affected work is released again. Keep a record of any customer or commercial approval needed for the change.
Keep the old version identifiable
Retain previous records in a clearly separated history so the team can reconstruct what happened. The active production location should have one unambiguous released version. Avoid relying on filenames such as final-new or final-final.
At the next production review, examine whether the change was caught before more work used the old instruction. The goal is a visible chain from the revised decision to every affected operation, with responsibility assigned at each handoff.
