Monitoring production is not micromanagement; it is catching problems while they are still cheap to fix.

Checkpoints

  • Materials in — correct grade, color and quantity received.
  • First articles — the first pieces off the line match the golden sample.
  • 20–60% complete — during-production inspection of random pieces.
  • Packing — cartons, labels and shipping marks correct.

What a good update contains

Quantity completed, photos of the line and finished goods, any problems and the action taken, and the updated ship date.

Our daily work log

For full-service orders we record every working day what we did, at what time, the result and the reason. You see the same information we see.

Remote vs. on-site monitoring

Remote monitoring — photos, videos and counts from the factory — is free and works for experienced suppliers with stable products. On-site visits are worth it for new suppliers, custom products and large orders, because they show things a photo cannot: material storage, how defects are handled, and whether your order is really on the line.

What a good progress check covers

  • Quantity of finished, in-process and packed units.
  • Material batches used and whether they match the approved grade.
  • First-off and random samples compared with the golden sample.
  • Defects found so far and what the factory did about them.
  • Updated ship date with reasons for any change.

An example daily log entry

10:15 — Checked incoming aluminum sheet at the workshop. Thickness 1.48–1.51 mm against 1.5 ± 0.05 mm: approved. Why: material errors are the most expensive defects to find late.

Entries like this — time, action, result, reason — are what our clients receive every working day. See Production Monitoring.

Your checklist

  • Agree checkpoints before production
  • Compare first pieces with the golden sample
  • Book a DUPRO for new suppliers
  • Track the ship date in every update
  • Act on slipping signals immediately

Frequently asked questions

How often should production be checked?

At minimum when materials arrive, when the first pieces come off the line, at 20–60% completion and at packing. High-risk orders deserve weekly visits.

What is a DUPRO inspection?

A during-production inspection at about 20–60% completion that catches defects while they can still be corrected on the line.
