Case Study: Spark Plug Supply for a government fleet in the Caribbean

Spark Plug for A government fleet in the Caribbean

A government fleet came to us with a spark plug programme for the Caribbean. 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

  • Reorders that did not match the approved sample
  • A fitment that looked right on paper and failed on the bench
  • Lead time that slipped twice before bulk started

How it was resolved

  1. The specification was rebuilt around Carbon Fibre Composite 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.

Spark Plug production run

Result

  • 50,000 pieces delivered inside the 5-week window.
  • Unit cost held within 2.0% of the original quotation.
  • Inspection-related rejection stayed under 0.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
