Lean Characteristics

Rinnai’s catchphrase “quality is our destiny” epitomises a corporate obsession with quality. They keep production of key components in-house at four of their own factories and seven manufacturing affiliates under the Rinnai Group umbrella. 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 hinging on the Toyota Production System, Total Productive Maintenance and Total Quality Management.
