Quantile Capital: Inspect More, or Fix the Line?
Quantile Capital manufactures asset management products in UK, running 821,376 units a year.
Internal quality checks reject 7.3% of output, at a scrap and rework cost of about £748 a unit. A further 1.8% of shipped units come back under warranty, each costing roughly £3281 once field service, replacement and admin are counted.
Two proposals are on the table. Engineering wants £28 M of one-off capital to re-tool the station where most defects originate. Quality wants £39 M a year of additional inspection headcount to catch more before shipment.
The plant manager is measured on unit cost.

Advise the plant manager. Your answer should provide:
- Analysis — the total cost of poor quality today, split by where it is detected, and the return on each proposal.
- Risks — what each option does not solve.
- Recommendation — which to fund, with a payback period.

Cost of poor quality = internal failure + external failure. Compare prevention against detection on payback, and note that inspection does not reduce the defect rate.
