Case Study: Window Switch Supply for a national parts importer in Latin America

Window Switch for A national parts importer in Latin America

A national parts importer came to us with a window switch programme for Latin America. 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

  • Premature wear on the first batch
  • A supplier who changed material without saying so
  • Reorders that did not match the approved sample

What was specified

PartWindow Switch
ClientA national parts importer
MarketLatin America
Volume2,000 pieces across 6 specifications
Base materialSemi-Metallic Compound
Sampling rounds2
Delivery window6 weeks from PO to ex-factory
ComplianceIATF 16949

How it was resolved

  1. The specification was rebuilt around Semi-Metallic Compound 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.

Window Switch production run

Result

  • 2,000 pieces delivered inside the 6-week window.
  • Unit cost held within 1.5% of the original quotation.
  • Inspection-related rejection stayed under 2.0%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
