Samples

Why sample feedback needs a decision log

Sample loops move faster when revisions, defects, approvals, and open questions are tracked in one place.

Sample work often breaks down because feedback is scattered across email, chat, photos, and internal comments. A decision log keeps the buyer and supplier aligned on what changed, what was approved, and what remains unresolved.

What a decision log should include

A sample decision log should record the sample version, supplier, date received, product reference, issue description, photo or measurement evidence, requested correction, supplier response, buyer decision, and next action.

This sounds basic, but it prevents a common problem: the buyer says a sample was approved while the supplier thinks only one defect was accepted, or the supplier changes a detail that the buyer never approved.

Use version names

Every sample should have a version name. Version 1 may be the supplier’s standard product. Version 2 may correct material or dimensions. Version 3 may confirm packaging. If the buyer approves only the product but not the packaging, the log should say that clearly.

Version control is especially important when several suppliers are being compared. Without it, photos, courier parcels, and comments become difficult to match.

Record decisions, not only opinions

Feedback such as “better,” “too cheap,” or “looks okay” is not enough for production. Turn comments into decisions:

Accepted as production reference.
Rejected because the material is wrong.
Revise color and send new sample.
Product accepted, packaging still open.
Accepted only if supplier confirms mass production can match it.

The final approved sample should connect to the written specification and inspection criteria.

Why this affects supplier selection

Sample behavior is a supplier signal. A supplier that documents corrections, answers clearly, and improves the sample in line with the brief is easier to manage during production. A supplier that ignores feedback, changes unapproved details, or cannot explain defects may create production risk even if the first price is attractive.

The decision log lets the buyer compare sample quality and supplier behavior together.

Keep open questions visible

Do not close a sample round while important questions remain open. Packaging, labeling, material, function, compliance, carton marks, and production lead time may all affect approval. If the buyer accepts a sample with open issues, list those issues and who owns them before deposit.

This guide is for sourcing and sample control. It does not replace product engineering tests, compliance review, lab testing, or buyer-side product approval authority.

Why sample feedback gets messy

Samples create many small decisions. The buyer may comment on material, dimensions, color, finish, packaging, labeling, function, accessories, smell, durability, or missing parts. Suppliers may answer in chat, send revised photos, or promise that “mass production will be correct.”

Without a decision log, the team loses track of which comment was accepted, which comment needs a new sample, and which comment is only a preference. Later, when production starts, the supplier may follow an older version or assume that silence meant approval.

What the decision log should include

A useful sample log does not need to be complicated. It should connect each issue to evidence and a decision.

Include:

Sample version or supplier name.
Date received and tracking reference.
Photo or file reference.
Issue or observation.
Buyer decision: approve, reject, revise, retest, or keep open.
Supplier response.
Required correction.
Owner and deadline.
Final production reference.

The log should be written in plain language. If the buyer cannot understand the decision six weeks later, the log is not doing its job.

Separate defects from preferences

Not every sample comment has the same weight. A defect means the sample fails a requirement. A preference means the buyer would like an improvement but may accept the sample if the change is not possible. A production requirement means the supplier must follow it in mass production.

Separating these categories prevents overreaction. It also helps the supplier understand what must change before approval and what can be discussed commercially.

Connect feedback to production

The final sample approval should become part of the order file. It should connect to the quotation, specification, packaging file, inspection criteria, and production follow-up checklist.

If production differs from the approved sample, the buyer needs a record. That record should show what was approved, what was rejected, which photos were used, and whether the supplier accepted the requirement in writing.

How to handle revised samples

Each revised sample needs a new version number. Do not overwrite the old decision. Keep the old sample notes visible so the buyer can see whether the revision fixed the issue or introduced a new one.

For complex products, create a simple table:

Version A: first sample, rejected for material and packaging.
Version B: material improved, packaging still open.
Version C: approved for production with carton mark correction.

This makes the final approval easier to defend internally and with the supplier.
