At present, we have rebuilt/operated the management system that was built by TQM as the quality management system and the environmental management system. The management systems have been individually certified by ISO.
We have also rebuilt/operated the occupational safety and health management system based on the notification by the Minister of Health, Labour, and Welfare, the occupational safety and health management system in the construction industry, or the like.
Furthermore, to respond to diversifying demands from society, we have built business systems in risk management, internal auditing, information security, etc. by using the mindset we learned from TQM.
