On-site related data such as customer service and returns are analyzed daily and monitored in real time at the analysis center. This enables us to promptly and accurately carry out quality improvement activities.

QS7
(Quality Solution 7 Days)

In case of quality issues, an “emergency permanent task force team (TFT)” is formed. The TFT improves and solves the given issue within 7 days, thus improving customer satisfaction.

Quality VOC Council

Unification the main quality VOC reception channels that are generated in the field, so that they can be improved applied quickly and accurately through regular consultation with related departments.

Improvement Responsibility System & Prevention Responsibility System

Our improvement responsibility system identifies and improves product defects. The prevention responsibility system prevents potential defects and helps us reduce the factors that cause them.

Quality Improvement Progress Management

Improvement progress is managed in real-time through our computer system, shortening the time for improvement processing. Cases of failure recorded in our database for continued quality improvement.

Quality Forecast System

Risks that may influence the quality of manufactured products are prevented according to weekly production plans.

Strengthening Verification in Product Lifecycle

Coway conducts verification of products from the view of lifecycle assessment. Stricter verification standards are applied, considering not only product safety, harmfulness, and hygiene but the environment where customers use the products.
Adopting Pre-Design Review
In order to enhance our products’ level of completeness and product quality, Coway conducts Pre Design Review (PDR) in the product development process, from product development to design, DPP and LPP, thus proactively managing risk factors. We work with external professionals in strengthening quality by identifying quality-related risks and new ways to improve the review system.
Expanding Reliability Test Plan Evaluation Meeting
Coway holds evaluation meetings that involve relevant personnel in development, reliability, and quality for an in-depth analysis of the reliability of new products, parts, and functions. At the kick-off meeting, the overall direction is set so as to decrease variability among test laboratories and evaluate all risk factors. At the completion meeting, improvement issues regarding testing standards and evaluation process are identified. Cases of failure are registered on the Stress-Strength Model (SSM) system and shared across the company.
Strengthening Verification of Debris Reliability
Coway conducts verification of potential debris in water and air purifiers and has developed testing methods. Causes for debris are categorized into corrosion, external contamination, etc., and analyzed accordingly. In 2016, 25 cases of debris in hot water tanks and corrosion were analyzed, and the safety of service goods was also examined.
Upgrading Verification of Breakdown and Defect
In order to analyze and prevent potential breakdown or defect during product use, Coway has established a verification process and conducts verification using state-of-the-art equipment. In 2016, 571 cases of broken PL were examined. The causes of breakdown in these cases were analyzed, and solution measures were prepared.

Upgrading Verification on Premium Products

Coway’s premium products are tested under very strict standards so that we can provide highly safe products to our customers. With the expansion of IoCare product development, we have secured professional test equipment and personnel, enabling us to evaluate the standard safety of our products and verify susceptibility to electromagnetic waves and electromagnetic field (EMF) safety from the customer’s point of view.

Operation of IoCare Quality Assurance System
We develop our IoCare products from the customer’s point of view, from product development to design, to strengthen our product quality. In 2016, we developed and operated our own shipment inspection and control system. We also analyzed patterns of sterilization duration and cycle, as well as patterns of product usage time. Furthermore, we improved the quality of our products by designing a smartphone application and establishing verification standards.
