Gemba (現場) is the Japanese word meaning 'the real place' — the shop floor, the store, the ground where the work actually happens. In lean philosophy, the principle 'go to gemba' is fundamental: problems are best solved where they occur, with the people who live them, observing the facts directly. Management done exclusively from reports and dashboards loses touch with the reality the data supposedly represents.
The concept became central to the Toyota Production System and was popularised globally by books such as Masaaki Imai's 'Gemba Kaizen'. 'Gemba walks' are regular visits by managers to the ground — not policing inspections, but opportunities to observe, ask, listen and learn. The informal rule: leave the director's chair for at least an hour a day.
Well-designed software does not replace gemba, but amplifies it. KORA Productivity brings the shop floor to the director's screen in real time — OEE, stoppages, output, defects. This visibility informs more focused gemba visits: the director arrives at the workstation with context, asks better questions, validates or refutes hypotheses. The combination of data and physical presence is more powerful than either alone.
