Control of production & service provision
Plain-language summary
Running production under controlled conditions — people know what to make, how to make it, how to check it, and the equipment and environment are up to the job.
What the clause is really asking
This is the heart of the standard for a manufacturer: production must not depend on luck or memory. Where the absence of an instruction could cause an error, an instruction must exist. Process parameters that matter must be defined and monitored. People must be competent, equipment suitable, and checks done at the right points — including validating processes whose output cannot be verified afterwards (welding, painting, heat treatment).
What auditors look for
Auditors walk the line. They stand at a workstation and ask the operator: what are you making, what does good look like, where is your instruction, what do you record? They compare actual machine settings against the documented parameters, check the instruction revision matches the controlled master, and chase 'special processes' for evidence of validation rather than inspection.
Typical evidence
Work instructions / control plans at the workstation; route cards or job travellers; process parameter logs; setup and first-off approval records; operator competence matrix; process validation records for special processes.
How to comply — recommendations
Build instructions from the process FMEA/control plan logic even outside automotive: control what can actually go wrong, not everything. Keep instructions visual — photos of good/bad beat paragraphs. Make first-off approval a hard gate. For special processes, define the recipe and re-validation triggers (new material, repair, drift).
Common nonconformities
Instruction at the workstation is an old revision; machine running outside documented parameters with no concession; no first-off record after changeover; 'experienced operator' used as substitute for any defined method; special process never validated, only inspected.
