The basis for manufacturing and all aspects of the process at Rinnai is to think and act from a scientific perspective. They have built a market-orientated production system that combines policy management, the quality control cycle, and continuous improvement proposal activities, based on a bottom-up approach heavily influenced by the Toyota Production System, and utilizing Total Productive Maintenance and Total Quality Management.
