Method

Gemba / genchi genbutsu

In French: Gemba (le terrain)

The gemba is the place where the work is actually done, and the gemba walk is the practice of going there to observe the process rather than reading the report about it.

What it is

Gemba means "the real place". In a factory it is the shop floor, in a bank the account manager’s desk, in a hospital the ward. The associated principle, genchi genbutsu, translates as "go and see for yourself": the reality of a process is not in its indicator, it is where it is carried out.

A gemba walk is not a visit. It is a framed observation, with a precise object — follow a part, time a cycle, watch what interrupts an operator — and a duration. Open questions are asked there; instructions are not handed out.

The rule that changes everything: you go to see the process, not the people. A gemba walk that produces remarks about the way someone works has missed its target, and the next one will take place in front of a workshop that has prepared itself.

What you bring back

Observed facts, not impressions: how many times the operator moved, where the part waited, what gap exists between the posted standard and the actual gesture. That gap is the most useful material one can bring back from a gemba, and it cannot be seen from any office.

An observation is worth something only if it leads to something. Coming back without changing anything, several times, turns the practice into a ritual — and the shop floor notices before management does.

The common mistake

Confusing it with an inspection round. As soon as the walk is perceived as a check, what works well is shown, tidying is done beforehand, and nothing more is learnt: one is observing a staging. The sign that the practice has taken hold is the day someone spontaneously shows you what does not work.

On the shop floor — Healthcare

In a care unit, following a single patient from arrival to being settled in showed seven staff trips to fetch equipment. None appeared in any indicator; all were known to the team, who had come to regard them as normal.

The other tools illustrated by this trade: healthcare and life sciences.

Frequently asked questions

What does gemba mean?

The Japanese word refers to "the real place", the one where the activity actually takes place: the workshop, the counter, the care unit, the warehouse. It stands in implicit contrast to the office and the dashboard, that is, to the places from which one believes one knows a process without ever having watched it run.

How does a gemba walk go?

A single object of observation is set in advance — follow a part, count interruptions, measure a cycle — along with a duration. On site, you observe and ask open questions, without giving instructions. You leave with quantified facts, and you come back to say what was done with them.

What is the difference between a gemba walk and an audit?

An audit checks conformity to a reference and produces a judgement: conforming or not. Shop-floor observation seeks to understand how the work is actually done, including when it departs from the standard, and that departure is precisely its most useful product. One grades, the other learns.
