A sample isn't a gift. It's a test, and you should know how you'll grade it before you open the box. Most first-time founders unbox a sample, feel excited or disappointed, and reply with "looks great!" or a vague list of worries. Neither gets you a better product. Here's a simple one-week plan to judge samples properly, especially when you're comparing two or three factories.
Day 1: Write the test before you open the box
Pull out your tech pack or spec sheet and turn it into a checklist: dimensions, materials, colors, logo placement, finishes, weight and packaging. For each measurement, write down the tolerance you'll accept, such as plus or minus 3 mm. If you don't have a spec, write down the five things a customer would notice first. That's your test.
Day 2: Measure everything
Now open the box. Measure and weigh every sample against your checklist, and photograph each one next to a ruler. Check colors in daylight against your reference swatch or Pantone chip, not under kitchen lights. Write down each miss as a number ("strap 6 mm short"), not a feeling ("strap feels short").
Days 3–4: Use it like a customer would
Put each sample through the life it will actually have. For a bottle, that might be a week of daily use, the dishwasher and a drop onto concrete. For apparel, it might be wearing it, washing it five times and checking shrinkage and color loss. For a bag, load it past its stated capacity and carry it. Things that fail in week one at home will fail in month one for your customers.
Day 5: Compare side by side and score
If you have samples from more than one factory, cover the labels and score them blind. A simple scorecard keeps the decision honest:
| Criteria | Weight | Factory A | Factory B |
|---|---|---|---|
| Accuracy to spec | 30% | ||
| Materials and feel | 20% | ||
| Construction and finish | 20% | ||
| Durability in use | 15% | ||
| Communication and turnaround | 15% |
Score each from 1 to 5. Communication belongs on the list: a factory that answered quickly and clearly during sampling usually behaves the same way during production.
Day 6: Send one clear set of comments
Put every change in one numbered document, with a photo and a measurement for each point. Mark each one as "must fix" or "nice to have". Factories handle one clear list far better than a stream of emails, and numbered comments make it easy to check the next round.
Day 7: Approve a golden sample, or don't
When a sample finally matches the spec, approve it in writing and make it your golden sample. Sign and date it, keep one at your end and ask the factory to keep a matching one. It becomes the standard every production unit is checked against, and the reference your pre-shipment inspection uses.
If it isn't right yet, don't approve it to save time. Every issue you let through on a sample shows up a thousand times in production.
A note on timing
Plan for at least two rounds of samples on a new product, and three for anything with custom tooling or a new material. That's normal. It's far cheaper to spend an extra two weeks on samples than to fix a production run.
