Zero
Parts-per-million defect rate

In today’s complex global supply chain, one of the biggest threats to productivity is the risk of a line stoppage caused by inconsistent or poor‑quality parts. Optimas International partnered with a leading automotive manufacturer to eliminate this risk, achieving a flawless zero parts‑per‑million defect rate.

Situation

During a high priority automotive mirror production project, the customer’s primary supplier stopped delivering to specification. The manufacturer urgently needed stronger quality assurance and a more resilient supply chain strategy to prevent costly downtime.

Solution

Optimas International deployed its quality and technical support teams to stabilise the programme. Leveraging deep industry expertise, we built a healthier, more diverse supplier mix and increased the use of locally sourced materials to reduce dependency on any single source.

To reinforce quality control, Optimas International implemented randomised product testing across all suppliers, ensuring every component met the customer’s standards.

Result

The outcome was a stronger, more reliable supply chain with reduced freight, shorter shipping times and improved operational stability. Most importantly, the customer maintained uninterrupted production and achieved a zero parts‑per‑million defect rate, restoring confidence in quality controls both during the project’s peak and well into future builds.
