Rinnai Corporation – Lean Characteristics
TQS, TPM
Rinnai’s catchphrase “quality is our destiny” epitomizes a corporate obsession with quality. They keep production of key components in-house at three of their own factories and 14 manufacturing affiliates under the Rinnai Group umbrella in Japan. By realizing this high in-house production ratio, they have control over quality and strive for zero-defect status.
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.
All employees participate in improvement and TPM efforts. They maintain a multi-product, mixed-flow production system based on actual demand. Through their own logistics network, they can realize timely delivery.
