Incoming inspection process flowchart (goods-in quality)

What the incoming inspection process flowchart (goods-in quality) process is

Incoming inspection is the quality decision taken on material an organisation has bought: does this delivery, of this part, from this supplier, against this purchase order line, meet the requirement well enough to be used? Everything around that decision exists to make it defensible later: which certificate arrived with the batch, how much of the delivery was sampled and why, what was measured or tested, and who authorised the material into stock or out of the building.

The scope is deliberately narrower than the processes on either side of it. Booking the vehicle in, counting the pallets, recording transit damage and raising the goods receipt note belong to the goods receiving process; incoming inspection begins once received material is sitting on inspection hold. Checking your own output (first-off, patrol and final checks against a control plan) is the quality inspection process, and the system that covers every inspection point at once is the quality control process. Deciding whether a supplier may be used at all, and for what, is vendor approval. This chart assumes the supplier is already approved and the order already placed, and answers one question about one consignment.

The template runs across five lanes (Goods-in, QC inspector, QC lab, Purchasing and Supplier) and six phases, from receipt through to the supplier performance record. Two failure points are worth designing out before anything else. Material that has been booked in but not yet inspected must not be pickable, which is why the inspection hold appears as its own step rather than as an assumption. And a concession has to be an authorised, recorded decision about one batch, not a verbal instruction to use it that quietly becomes the new specification. Treat the chart as a starting point for your own procedure; it is not evidence of compliance in itself.

What this flowchart covers

In this template

• Five swimlanes (Goods-in, QC inspector, QC lab, Purchasing and Supplier) across six phases: Receipt, Documentation, Sampling and inspection, Testing, Disposition, and Records and supplier feedback.
• Receipt handled as a quality hold rather than a stock movement: the delivery is moved to inspection hold before the QC inspector checks the quality documents against the purchase order line.
• A three-way "Certificate of analysis supplied?" decision: supplied goes to a check of the certificate against the delivered batch, not required goes straight to sampling, and missing puts the delivery on hold until the certificate arrives and returns it to the same decision.
• Sampling to the inspection plan and the supplier's risk level, visual and dimensional checks, then a "Laboratory testing required?" decision that either sends the sample to the QC lab or goes directly to the conformance call.
• A "Conforms to specification?" decision splitting into acceptance and release to stores, or quarantine of the delivery and a supplier nonconformance report.
• The nonconforming route: a "Nonconforming disposition?" decision branching to concession or return, a "Concession approved?" gate that falls back to return when refused, purchasing arranging the return and replacement, the supplier responding to the nonconformance report, and every delivery (accepted or rejected) updating the supplier performance record before the inspection record closes.

When to use this template

• You are writing or revising a goods-in inspection procedure and need one picture of who holds the material, who samples it, who tests it and who may release it.
• Uninspected material is reaching production or the picking face, and you need the inspection hold, the stock status behind it and the release step drawn explicitly rather than assumed.
• You are bringing on a new supplier or a safety-critical part and want the amount of inspection to follow supplier risk instead of habit.
• Concessions are agreed informally, so months later nobody can say who authorised use-as-is material, on which batch, or whether the customer was told.
• An auditor or customer has asked how you verify purchased material before use, and the current answer is spread across a work instruction, a spreadsheet and people's memories.

How it works

1. Rename the lanes to your roles

   Replace Goods-in, QC inspector, QC lab, Purchasing and Supplier with the roles that genuinely exist. If testing is subcontracted, that lane is an external laboratory with a turnaround time worth stating. If one person receives and inspects, merge those lanes rather than drawing a handover that never happens.

2. Attach the inspection plan to the sampling step

   For each part or material group, record the characteristics inspected, the method and gauge, the sample size, the accept and reject criteria, and the specification revision in force. State plainly where you inspect every unit instead of sampling, and where you rely on the supplier's own test data.

3. Write the supplier risk rule that changes the sample size

   Decide what puts a supplier on reduced, normal or tightened inspection — new supplier, new part, an open nonconformance, safety-critical characteristic — and, just as important, what brings them back. Attribute sampling standards such as ISO 2859-1 and ANSI/ASQ Z1.4 define switching between normal, tightened and reduced inspection from recent lot history; if you do not use one, write your own trigger down so tightened inspection does not become permanent by default.

4. Say which materials need a certificate, and what makes one valid

   List the material groups that require documentation and the type required. For metallic products EN 10204 distinguishes a 2.1 declaration of compliance with the order, a 2.2 test report, and 3.1 and 3.2 inspection certificates based on specific inspection; chemicals and consumables normally arrive with a certificate of analysis. Whichever applies, a valid certificate carries the batch, lot or heat numbers actually delivered and the specification revision named on the purchase order.

5. Name the concession authority and its limits

   Record who may authorise use-as-is material, up to what risk or value, and when the customer has to be told because the requirement affected is theirs. Make it explicit that a concession covers one batch and one deviation, and that it is recorded with the quantity, the reason and the name of the person who authorised it.

6. Decide what the supplier record captures and where it is reviewed

   Pick the fields that make inspection results useful later — conformance rate, nonconformance count, response time to a report, cost of sorting or rework — and name the supplier review meeting that looks at them. That is the forum where a risk level changes, re-approval is triggered or a recurring problem becomes a corrective action, and without it the record is only filed.

Frequently asked questions

What is the incoming inspection process?

It is the quality verification applied to purchased material before it can be used. The delivery goes to inspection hold, the quality documents are checked against the purchase order line, and a certificate is verified against the delivered batch where one is required. A sample is then drawn to the inspection plan and the supplier's risk level, checked visually and dimensionally, and tested in the laboratory where the characteristic cannot be judged by eye. If the material conforms it is accepted and released to stores. If it does not, it is quarantined and reported to the supplier, and someone decides between accepting it under an authorised concession and returning it for replacement. Either way, the result updates the supplier performance record before the inspection record is closed.

What is the difference between incoming inspection and goods receiving?

Goods receiving is a logistics and commercial transaction: unload, count, check for transit damage, match the delivery to the purchase order and raise the goods receipt note so the invoice can be matched. Incoming inspection is a quality decision about whether the material meets its specification. Between the two the material should sit on inspection hold — booked in, visible in the system, but not available to pick. Where the two are run as one step, receipted stock becomes usable stock the moment the paperwork clears, and uninspected material reaches the line.

Does every delivery need a certificate of analysis?

No. The requirement comes from the material and from what the purchase order asked for, so most organisations define it per material group rather than per delivery. Certificates of analysis are normal for chemicals, raw materials and regulated consumables; for metallic products EN 10204 sets out the document types, from a 2.1 declaration of compliance with the order and a 2.2 test report through to 3.1 and 3.2 inspection certificates based on specific inspection. Many purchased parts need only a certificate of conformity, or nothing at all. What matters is that receiving a certificate is not the same as verifying one: it should carry the batch, lot or heat numbers actually delivered and the specification revision named on the order, and someone should be named as having checked that it does.

How much of a delivery should be inspected?

Enough for the risk, decided in advance rather than at the dock. Attribute sampling standards such as ISO 2859-1 and ANSI/ASQ Z1.4 give a sample size from the lot size, an inspection level and an acceptable quality limit, and define how a supplier moves between normal, tightened and reduced inspection as their recent record changes. Well-performing approved suppliers can move to reduced or skip-lot verification provided the rule that re-tightens them is written down. Safety-critical or non-recoverable characteristics may justify inspecting every unit. Sampling gives confidence about a lot rather than a guarantee about every item in it, and it is worth saying so in the procedure so the limits of the check are understood.

What happens when incoming material fails inspection?

Quarantine first, paperwork second: the material is segregated physically and its status changed in the system so it cannot be picked, then a nonconformance report goes to the supplier with the part number, batch, purchase order, quantity affected, the requirement, the actual condition and the evidence. Disposition follows. Returning the material puts purchasing in charge of the return and the replacement, which re-enters this process as a new delivery. Accepting it as it stands is a concession, and it needs an authorised, recorded decision covering one batch. ISO 9001:2015 clause 8.7 deals with control of nonconforming outputs and expects the nonconformity, the action taken, any concession obtained and the authority that decided it to be documented, with the customer informed where the requirement affected is theirs. In both cases the supplier responds to the report and the outcome is recorded against their performance.
