Quality Management System
Our basic thinking on quality
COSEL has established the quality policy “Creating customer confidence through our products and services” based on our corporate philosophy (organizational goal) of “Responding to society’s trust through our unwavering commitment to quality.”
The bases of activities for quality improvement are product reliability and delivery of peace of mind to customers. We believe that these will enable us to earn the trust of society.
To realize this policy, we have identified the concept of Total Quality Management (TQM) as a pillar of management, and we aim to link this concept to our sustained growth as an enterprise through raising the levels of quality of not only our products and services but also our work and our management.
COSEL will strive to improve quality at all stages from product planning and development through production, sales, and service, in order to provide our customers with attractive products and services that win their trust and deliver peace of mind and satisfaction.

We have earned ISO 9001 international certification by establishing a quality management system, and we continue to implement thorough quality management. We began application of the 2015 version of ISO 9001 in October 2016. We successfully acquired certification under the 2015 version following a transition audit in June 2017.
