Quality Assurance Activities
At SK-Electronics, each business division and group company establishes a Quality Manual in line with the Quality Policy to maintain a robust quality management system.
Conducting Quality Audits to Ensure Reliable Quality Assurance
Our two manufacturing sites in Japan (Kyoto Plant and Shiga Plant), as well as our overseas group plant (Finex Plant (Tainan, Taiwan)), are certified to the international standard ISO 9001 for quality management systems. Each organization thoroughly implements the PDCA cycle—planning improvement, implementing improvement, and evaluating results—to ensure product quality, drive continuous improvement, and prevent quality issues before they occur. We also continue to conduct audits to verify the effectiveness of our QMS.
- Internal audits conducted by trained internal quality auditors (once per year)
- Recertification and surveillance audits conducted by external certification bodies (once per year)
- Regular verification of quality assurance structures at each site
Supplier Quality Audits to Ensure Reliable Quality Assurance Activities
Our Quality Assurance Division maintains a global framework to drive quality improvement. For example, for purchased parts and materials, we operate a supplier qualification program—together with the procurement functions of each business division—to evaluate and certify suppliers’ process quality in order to ensure global quality.
Early Detection and Prevention of Critical Complaints and Preparedness for Potential Incidents
We manage customer inquiries and nonconformance information to enable the early detection of critical quality issues and to prevent similar issues from occurring.
Quality Meetings to Ensure Effective Quality Assurance Activities
Quality meetings are held to share quality-related information and to discuss and decide important matters related to corrective and preventive actions.
System Improvement Committee to Strengthen the QMS
The System Improvement Committee discusses and decides important matters related to the exchange of information and implementation of measures in order to align understanding across departments when establishing, revising, or discontinuing QMS-related standard documents that span multiple departments.
