On May 27, 2021, we held our latest Quality Lecture online, and over 700 Group employees from Japan and overseas participated. The lecture targeted mainly managers and supervisors on the front lines of quality management and quality assurance. The theme was human error and aimed to enhance everyone’s awareness of preventing problems. External lecturers explained, with examples, ways to eliminate causes of human error, factors that invite error, and how to prevent errors from leading to accidents.
