NOK's Quality Management Behind the Award

NOK promotes quality management at its global sites using video equipment and digital tools. By continuously implementing improvement activities tailored to each site's challenges—such as visualizing expert skills, systematizing training, and analyzing root causes during equipment downtime—the company ensures consistent product quality.

● Visualization and Improvement Using Video Equipment

- Analyzes worker-eye-view videos to visualize and standardize expert skills ('know-how'), enabling reliable skill transfer.

- Accurately identifies 'difficult tasks' from visual data and improves work procedures and environments accordingly.

- Reviews recorded footage during equipment stoppages to clarify the root causes of malfunctions.

● Systematized Training and On-Site Inspections Using Digital Tools

- Establishes a tablet-based repetitive training system at production sites to solidify knowledge and skills (standardization).

- Conducts close on-site inspections by quality managers to detect minor abnormalities early and rapidly implement improvements, thereby elevating overall quality standards.
