This marks the fourth time NOK has received the excellence in Quality award, in recognition of quality management that delivers stable quality across five global sites. NOK will continue strengthening its global quality management and driving further improvements going forward.

The Quality Management Behind the Award

At its sites around the world, NOK promotes quality management using video equipment and digital tools. NOK continues improvement activities tailored to the challenges at each site: visualizing the transfer of skilled expertise, systematizing education, and analyzing the root causes of equipment stoppages. These initiatives drive stable quality as a result.

Visualization and Improvement Using Video Equipment

- Analyzing footage shot from the worker's own viewpoint to visualize and standardize the instinct and know-how of skilled workers, ensuring reliable skills transfer.
- Accurately identifying hard-to-perform tasks from point-of-view footage, and improving work procedures and the work environment accordingly.
- Reviewing recorded footage of the moments before a temporary equipment stoppage to pinpoint the true cause of the issue.

Systematizing Education and Close On-Site Inspection Using Digital Tools

- Building a system of repeated training via on-site tablets to embed and standardize knowledge and skills.
- Detecting minor abnormalities early through close inspection by quality managers, raising quality levels through prompt improvement.
