What is a Gemba Expert and why it is essential for Lean organizations

Gemba (現場) experts are people who specialize in working on and with the gemba. What exactly is Gemba? It's a Japanese term that literally means "the actual place," or: the place where the work actually happens (the shop floor, operations, practice).

In Lean, gemba revolves around the principle: go and see where the work happens instead of just relying on reports or assumptions.
