A Gemba walk is a planned visit to the place where work happens. In Japanese, gemba means the actual place. The aim is to understand real process conditions by observing the work and asking open questions.
In manufacturing, a walk may focus on safety, quality, workflow, delays, handoffs, or obstacles. It is a way to learn and support the team, not an inspection of individual performance.
A useful walk follows a process, listens to the people doing the work, records evidence, and agrees on an action and owner. Follow-up turns observations into part of the 持续改进过程.
