Based on the Four Basic Quality Assurance Principles, we have established a system for quality assurance and improvement activities throughout the entire Group, including the appointment of a quality assurance promotion manager in all business group headquarters. We have also formulated quality assurance guidelines to ensure compliance with quality assurance legislation and standards and further develop quality improvement activities.
Worldwide manufacturing bases take responsibility for the quality assurance of each product and are implementing concrete improvement measures. At the level of management, we also regularly report on the status of quality at meetings of executive officers.
Promotion of Quality Assurance and Improvement Activities (in Mitsubishi Electric alone)
Worldwide manufacturing bases take responsibility for the quality assurance of each product and are implementing concrete improvement initiatives in relation to quality assurance measures (quality management) for processes at each stage, from market surveys regarding Mitsubishi Electric products, through product planning, development and design, manufacturing, transportation, storage, installation, maintenance and servicing, and education, to the disposal of the product.
In addition, in operating our Quality Management System (QMS), we regularly check our PDCA cycle with reference to ISO and other international certification standards, seeking to realize ever higher quality by process improvement.
