Radar Detector for An online marketplace seller in Southern Africa

An online marketplace seller came to us with a radar detector programme for Southern Africa. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • Documentation that arrived after the container shipped
  • A fitment that looked right on paper and failed on the bench
  • A supplier who changed material without saying so

Volume10,000 pieces across 6 specifications
Base materialStainless Steel
Sampling rounds4
Delivery window8 weeks from PO to ex-factory
ComplianceECE R90

How it was resolved

  1. The specification was rebuilt around Stainless Steel and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Radar Detector production run

Result

  • 10,000 pieces delivered inside the 8-week window.
  • Unit cost held within 2.0% of the original quotation.
  • Inspection-related rejection stayed under 1.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.
