Quality Management System

Quality Management System

Coway has established and been implementing quality management principles to continuously improve product safety and performance. From the R&D stage to the use and disposal of products, we are inspecting reliability, safety and environment performance. In addition, we are striving to achieve customer satisfaction by securing product performance safety factors, minimizing certification risks, and endeavoring to optimize quality standards from the viewpoint of customers and user environment.

Quality Management Exclusive Organization

Coway has formed and been operating a quality management headquarters dedicated to quality innovation so as to improve customer trust and meet expectations regarding the quality of products and parts. The quality management headquarters carries out quality management activities and monitors potential quality issues that may arise from the process of developing products and from products that have already been sold to identify post-production quality issues and preemptively respond to such issues.

Organizational Chart of the Quality Management Department

Infinite Responsibility Committee

Coway operates the ‘Infinite Responsibility Committee’ to provide customers with better quality products and services. The Infinite Responsibility Committee is attended by the CEO and core executives from our business organizations to share quality issue agendas. The issues discussed at the Committee are grafted onto the company-wide processes to promptly address quality issues.

Quality Management Certification and Verification

Coway conducts an internal audit every year based on ISO9001, a global standard certification, and receives *QCAS-based evaluations from external experts through its challenge of becoming a 'Company with Excellent Quality Competitiveness'. Through these internal audits and evaluations from external experts, we identify what needs to be improved, make such improvements and provide the highest level of products to our customers.

CASE

Selected as an ‘Excellent Company with Product Quality Competitiveness’ at the 49th National Quality Management Competition in 2023.

In recognition of Coway‘s efforts to drastically reduce the defect rate through a total sample inspection at the stage of verifying developed products, we were selected as the 11th company with excellent quality competitiveness at the 49th National Quality Management Competition in 2023. In the past, each of the organizations in charge of development, quality, and production conducted a separate sampling inspection on its own. However, starting from this year, we introduced a company-wide integrated verification system that integrates and operates verification capabilities of the three organizations and conducts thorough inspections of all developed products. Through this, we standardized verification methods and norms as to each of the parts and performances and improved product quality by reducing sample errors.

Quality Management Activities

Quality Management Programs

Coway operates various quality management programs to provide high-quality products and services. In order to prevent defects related with durability and performance of products and parts, which may occur depending on the period of time for which they were used by customers, we conduct mass-production reliability tests periodically and improve quality. In addition, we use out IoT platform to ascertain customers‘usage environments and patterns and reflect them in reliability test methods. And we also conduct defect-linkage analyses for the improvement of quality and the development of new products. When developing new products, we strive to improve the quality of products and the level of safety by verifying and enhancing quality from the perspective of customers through the ‘Quality Expert Committee.’ And we identify major quality VOCs received through the ‘Quality VOC Committee’ so as to make improvements.
