To continue providing products and services that meet customer needs, the "Quality Management System (QMS)" is essential. The QMS helps us promote systems that differentiates our business and improve our organizational structure as well as acquiring ISO 9001 certification.
For medical device products, we are working to obtain ISO 13485 certification, an international standard for the medical device industry, by developing the systems and conducting internal audits, focusing on compliance with applicable laws and regulations.

Small Group Improvement Activities

As part of our small group improvement activities, we are developing QC circle activities as "NQC Activities." (N denotes an initial letter of Nittoku).
NQC activities organize teams according to the problems and challenges at hand, with activities aimed at solving and achieving them. In addition to making tangible and intangible contributions to management, they also contribute to fostering employees.
The level of our activities has improved, with a gold medal at the All-Japan QC Circle Competition and the QC Circle Kaoru Ishikawa Award.
In addition, we are introducing the NQC Station, an IT tool for interactive communication, in order to strengthen NQC activities. We have systematized the proceedings of our activities and made it easy to understand the situation at hand. A portal site function has also been provided to enable circle members to obtain useful information and materials for their activities at any time.

To improve our employee’s quality control and foster employees capable of creating products and services that meet the needs of our customers and society, a variety of training is conducted related to quality control based on the concept of "manufacturing is fostering people".
Beginning with training for engineers to acquire practical skills in product realization concepts and procedures and quality control methods, as well as periodic training sessions, depending on the type of job and level of responsibility. Also, to improve through continuous upgrading of knowledge and practical skills required to maintain and improve quality. Aiming to improve the overall quality of the product.
We also offer our suppliers quality training and practical support for problem-solving so that they provide us with consistently high-quality parts and materials based on continuous quality improvement.

Appropriate measurement is an essential part of manufacturing. In order to obtain reliable measurements, it is important that employees involved in manufacturing know the correct measurement techniques and proper measurement management.
Therefore, we are strengthening our quality assurance system by nurturing human resources who understand the importance of measurement management and have correct measurement techniques, managing the accuracy of measuring instruments, and improving the measurement management system to improve and stabilize accuracy.

Monozukuri (Manufacturing) Education

To help trainees, acquire the necessary knowledge and skills at the right time, the Monozukuri Education and Training Center has a curriculum that covers the topics of safety, quality, maintenance, and improvement.

Safety training is conducted with zero industrial accidents in mind, with the guideline of "cultivating employees who can think and anticipate danger by honing their sensitivity before they act". We are working to improve the content of our education and training by introducing virtual reality (VR) and incorporating hands-on training to give employees more realistic experience of accidents such as falls and other accidents.
We are striving to provide valuable education while being flexible. We responded to the COVID-19 pandemic by introducing web-based lectures and other methods.
