Quality agreements: settling who decides what conforming means

Fixing what conforming means, against which document

Almost every quality dispute reduces to two parties applying different definitions of acceptable. The agreement's first job is to name the controlled specification, the drawing revisions, the test methods, the sampling approach, the limit samples for anything subjective, and the measurement equipment or laboratory whose result is authoritative when the two sides disagree. Where an external test is involved, saying whose laboratory decides prevents a stalemate in which each party holds a certificate contradicting the other. This section is technical rather than legal, and it is the one most often left as a reference to documents that have since moved on.

Who may release, who may deviate, and who must ask

Production throws up borderline material daily, and somebody decides whether it ships. Write down which decisions the manufacturer may take alone, which require your written concession before shipment, and who on each side holds that authority by name or role. Include how a concession is requested, what evidence it carries, whether it applies to one batch or becomes a habit, and how it is tracked so that a temporary allowance does not silently turn into the new standard. Plants that lack this either escalate everything, which nobody sustains, or release quietly, which you discover through a customer.

Change notification is the obligation most often breached

Manufacturers improve processes, requalify materials, move equipment between buildings, replace a sub-tier supplier and adjust parameters, usually for good reasons and usually without thinking of your product as affected. Define which categories of change require notice to you before implementation rather than after, covering material and component sources, process route, tooling, equipment, site, key sub-suppliers and inspection methods. Then decide what evidence accompanies the notification and how long you have to respond. Buyers discover the absence of this clause when a field failure traces to a substitution nobody told them about, which is the worst moment to establish that no obligation existed.

Records, traceability and the right to look

Agree what production evidence is generated, what is retained, for how long, in what form, and what you may see. Traceability granularity is a practical decision with real cost: linking finished units to material batches, machines, shifts and tooling cavities is straightforward if designed in and close to impossible retrospectively, and it determines how wide a recall has to be. Cover access too, meaning routine reporting, the right to audit, and whether that extends to sub-tier sites. When a manufacturer holds records you cannot obtain, your ability to investigate your own product failure depends entirely on their cooperation.

Complaints, investigations and failures that reach the market

Set out how a customer complaint travels back to the plant, who investigates, what an acceptable investigation contains, and how conclusions are communicated. Define the escalation path when something serious appears, including who each side notifies internally, who speaks to regulators where a product is regulated, and what support the manufacturer provides if units must be retrieved from the field. These provisions are used rarely and matter enormously when used. Draft them with legal input alongside the technical staff who will run them, because a procedure written only by lawyers tends not to survive its first genuine emergency.

Frequently asked questions

Is a specification not enough on its own?

A specification describes the product. It does not say who is allowed to decide a borderline batch is acceptable, what notice you receive before a process changes, how long batch records are kept, or what happens when a complaint arrives. Those are allocations of responsibility rather than technical requirements, and they are what people argue about under pressure. In regulated sectors the expectation of a documented split of quality responsibilities is stronger still, and your regulatory adviser should confirm what applies to your product.

Who should sign a quality agreement on each side?

The people who can actually deliver the obligations, which normally means quality leadership on both sides, with commercial sign-off to confirm it does not contradict the supply terms. Watch for the failure mode where a purchasing team negotiates commitments the plant never sees, or a quality team agrees an inspection regime nobody priced. Both documents should be reviewed together by both functions, and legal input is worth having on the sections dealing with market withdrawal and access rights.

How do we stop the agreement becoming a document nobody reads?

Give it an owner, a review date and a place in the routine business review, then test it occasionally. Ask the plant to produce a batch record from a random shipment, request a change notification history, or check that the limit samples on the line match the revision you released. Drift is normal and correctable when found early. What causes harm is discovering during an investigation that the agreed practice stopped being followed long ago and nobody on either side noticed.
