Case Study: Brake Booster Supply for a taxi fleet in Eastern Europe

Brake Booster for A taxi fleet in Eastern Europe

A taxi fleet came to us with a brake booster programme for Eastern Europe. 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 specification nobody had written down
  • A supplier who changed material without saying so

ClientA taxi fleet
MarketEastern Europe
Volume20,000 pieces across 3 specifications
Base materialPVC Coated Fabric
Sampling rounds4
Delivery window4 weeks from PO to ex-factory
ComplianceECE R90

How it was resolved

  1. The specification was rebuilt around PVC Coated Fabric 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.

Brake Booster production run

Result

  • 20,000 pieces delivered inside the 4-week window.
  • Unit cost held within 4.5% 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

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
