The auditor is not one day a year, it is a permanent regime

An automotive supplier does not live through one audit a year: it lives in a permanent regime — certification, customer process audit, surveillance, and part approval for every new part number. The real cost is not the auditor's day, it is the two weeks beforehand with several qualified people rebuilding traceability. With iLEAN, every critical change generates its dossier on its own, at the moment it happens, and Agents files it by certification standard and by part number.

The problem

The finding does not come from running the process badly. It comes from not being able to prove it.

The auditor asks for proof, the plant produces folders, and the finding does not come from running the process badly but from being unable to demonstrate it. It is the classic frustration of any quality manager: the process was fine, the evidence was not organised. Rebuilding that evidence consumes first-piece records, current control plans, up-to-date calibrations and preventive maintenance on tooling, all scattered across folders, spreadsheets and systems that do not talk to each other. And the consequences of a major finding are not paid in fines. They are paid in programmes that never get nominated: in automotive, certification status is a condition of access to tenders, not an ornament.

  • An automotive supplier does not live through one audit a year: it lives in a permanent regime across certification, customer process audit, surveillance and part approval for every new part number.
  • The real cost is not the auditor's day. It is the two preceding weeks of several qualified people rebuilding traceability.
  • The evidence is scattered across folders, spreadsheets and systems that do not talk to each other: first-piece records, current control plans, up-to-date calibrations, preventive maintenance of tooling.
  • And the consequences of a major finding are not paid in fines: they are paid in programs that do not get awarded. In automotive, certification status is a condition of entry to tenders.
How it fits the IRIS system

Edge and Connect capture; Agents files against the clause that requires it.

Edge + Agents, a permanent evidence pack.

The consequence is elegant: if the dossier was not generated, the critical change was not validated, and therefore the line did not start. Evidence stops being a later formality and becomes a by-product of the process itself.

  • Edge supplies the objective evidence: before and after photos of every critical point at every changeover, the image of the detected defect, the state of the tooling.
  • Connect supplies the context: order, heat number, press and welding parameters, the signature of whoever validated, the calibration status of the instrument used.
  • Agents stitches the two together: it files each piece of evidence against the clause of the standard that demands it, indexes it by part number, by lot and by period, and generates the dossier for the audited period on demand.
  • The auditor logs into a web page, filters and downloads. Zero human work after the fact.
  • An elegant consequence: if the dossier was not generated, then the critical change was not validated, and so the line never started. Evidence stops being a follow-up chore and becomes a by-product of the control itself.

Impact estimate

Estimated impact — to validate with your own numbers.

The block below is an estimate to be validated against your plant's actual data. We put it forward so the committee has an order of magnitude; we refine it during the assessment.

  • Estimated payback 6-12 months, depending on your plant's audit frequency.
  • Person-weeks of preparation recovered, audit after audit.
  • Nonconformity risk from a documentation gap eliminated.
  • The larger value is not the payback: it is protecting certification and the award of future programs, on a multi-year horizon.

estimated payback 6-12 months depending on audit frequency, from the person-weeks of preparation recovered. The larger value, however, is protecting certification and the nomination of future programmes, whose horizon is multi-year and far exceeds the cost of the system. *Estimate to validate.*

And the fair question from the production manager

«Isn't this just another document manager, and we already have those?» — the difference is direction. A document manager stores what somebody decides to upload, after the fact. Here the evidence is generated on its own the instant a critical change is validated, and Agents files it against the clause that requires it. Nobody has to remember to upload anything, which is exactly where the gaps open today.

Frequently asked questions

What people ask about the evidence pack

Does it work for IATF 16949 and for customer audits too?

Yes. The evidence is the same; what changes is the structure it is indexed against. Agents files each item against the clause of the standard that requires it, and the same material serves the customer process audit.

Does the auditor get access to the whole system?

No. They enter a view scoped to the period and scope of their audit, filter and download. They do not browse the plant's systems.

What about evidence from before deployment?

It stays where it is. The evidence pack builds from day one forward; earlier history can be brought in if it is worth it, but it is not a prerequisite to start.

Does it help with part approval for a new part number?

Yes, and it is one of the biggest time savers, because approval documentation is exactly what gets rebuilt by hand against the clock every time a new part number comes in.

Does it need the other eleven cases deployed?

No, but the more there are, the more complete the dossier. With Edge and Connect on the critical points you already cover the bulk of what an auditor asks for.
