The Three Reals, or (San-gen Shugi in Japanese), is a profound yet simple philosophy.  It’s a core principle of lean management that requires going to the actual place (Genba), seeing the actual thing (Genbutsu), and understanding the actual facts (Genjitsu).

Its global influence stems from its powerful simplicity. In a world of digital data and remote management, The Three Reals provides a vital counterbalance. It reminds us that no amount of data can replace firsthand observation. This hands-on approach to problem-solving is a universal practice that cuts through assumptions, enabling true root-cause analysis and continuous improvement.
