Power Window Motor for An e-commerce seller in East Africa
An e-commerce seller came to us with a power window motor programme for East 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
- Lead time that slipped twice before bulk started
- Warranty claims traced back to a single lot
- Premature wear on the first batch
What was specified
| Part | Power Window Motor |
|---|---|
| Client | An e-commerce seller |
| Market | East Africa |
| Volume | 50,000 pieces across 6 specifications |
| Base material | Natural Rubber |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | CCC |
How it was resolved
- The specification was rebuilt around Natural Rubber and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.
Result
- 50,000 pieces delivered inside the 8-week window.
- Unit cost held within 3.0% 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.
