IATF audit always ready: the dossier closes as it happens

The problem

The cost of the audit is not the audit.

The evidence exists, but it is scattered across paper, spreadsheets, the MES and people's memory. That is the honest diagnosis of almost any certified plant. The cost of the audit is not the audit: it is the person-weeks before, repeated for every customer that audits. In a Tier-1 with several OEMs, that multiplies by the number of customers entitled to audit. And in the worst case — a field investigation — the clock runs in hours, not weeks. There, the difference between having the dossier and having to build it is the difference between bounding the problem and widening the containment out of caution.

• The evidence exists, but it is scattered across paper, spreadsheets, the manufacturing system and people's memory. That is the honest diagnosis of almost any certified plant.
• The cost is the preceding person-weeks, repeated for every customer that audits.
• At a Tier-1 with several OEMs, that multiplies by the number of customers with audit rights.
• And in the worst case — a field investigation — the clock runs against you from the first minute.

How it fits the IRIS system

Edge and Connect capture; Agents organizes by standard.

Agents working on what Connect and Edge already captured. Not one more record is added: what already exists gets organised. Step 1 — Raw material already captured. Before and after photos of the changeover points, part-by-part leak curves, signed crimp parameters, metrology dimensions and process capability, certificates for the material consumed, the content actually marked, the first-piece record and the shift log. Step 2 — Mapping by clause. Agents links each piece of evidence to the clause of the standard that demands it: automotive quality management standard, product approval, customer-specific requirements, environment and safety. Step 3 — Publication. The pack publishes by batch, by part number or by period, and downloads from the web. It serves the certification body and the customer audit equally well. Step 4 — Gap detection. If a batch lacks a piece of evidence its standard requires, the gap appears when it is produced, not on the day of the visit. The documentary nonconformity gets prevented.

Every lot and every change leave their dossier closed at the moment they happen. Anything rebuilt afterwards inherits the gaps of whatever nobody wrote down — and it is precisely in the assembly that nonconformities appear.

Before and after

Today's preparation versus the permanent dossier

Aspect	Today	With iLEAN Agents
Audit preparation	1-2 person-weeks	Hours of review
For each auditing customer	Repeated in full	Same evidence, another view
Where the evidence is	In four different places	One downloadable package
Documentation nonconformity	Found during the audit	Detected when it occurs
Field investigation	The clock against you	The dossier already exists
Process capability	Printed and hunted down	In the package

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 recovery of 1 to 2 person-weeks per audit and per auditing customer.
• Estimated payback 5-10 months counting only that preparation time.
• At a Tier-1 with several OEMs, the saving multiplies by the number of customers with audit rights.
• And in a field investigation the dossier already exists instead of starting to be built with the clock running.

Estimated recovery of 1 to 2 person-weeks per audit per auditing customer, with estimated payback of 5 to 10 months counting only that preparation time. *Estimate to validate* against the plant's annual audit count. On top of that comes the ability to answer a field investigation in hours.

And the fair question from the production manager

«Isn't this just another document manager?» — the difference is direction. A document manager stores what somebody decides to upload, after the fact, and inherits the same gaps. Here the dossier closes the instant the lot or the change happens, and what Agents does is reorganize it for whichever standard asks.
