Case Study: Alternator Supply for a motorcycle assembler in North America

Alternator for A motorcycle assembler in North America

A motorcycle assembler came to us with a alternator programme for North 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

  • Documentation that arrived after the container shipped
  • Packing that arrived crushed at the port
  • Premature wear on the first batch

Volume2,000 pieces across 2 specifications
Base materialReinforced Nylon
Sampling rounds4
Delivery window5 weeks from PO to ex-factory

How it was resolved

  1. The specification was rebuilt around Reinforced Nylon 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.

Result

  • 2,000 pieces delivered inside the 5-week window.
  • Unit cost held within 4.5% 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.
