Gemba and Genchi Genbutsu: going to see where things happen

In one line

To improve something, you have to go to where it happens: look at the real work, ask why, and decide based on facts, not from behind a desk.

What it is

The CFR de Lugo material presents three Japanese words that go along with Kaizen:

• Gemba: literally the "actual place," where the work is done, value is created and problems arise. In a manufacturing company it is the factory itself; it can also be the shop, the construction site, a hospital operating room, the warehouse and even the office.
• Genbutsu: the real product being made.
• Genjitsu: knowing the facts.

Genchi Genbutsu ("go to the place and see the real thing") is principle 12 of Liker's The Toyota Way: go and see for yourself in order to understand the situation thoroughly. It is the basis for decisions in the Toyota Production System and the reason why analysis tools, such as the 5 Whys, are done in front of the problem and not in a meeting room.

How it is applied: the Gemba walk

According to the CFR de Lugo material, the Gemba walk is a key piece of the Kaizen process because it puts you in contact with the reality of production: improvements are more likely to work when you go to the place where the problems occur instead of staying behind the desk. The walk should cover three aspects that the material attributes to Jim Womack:

1. Go and see: how the whole process works, and whether processes and people are in line with each other.
2. Ask why: learn the operations in detail so you can propose solutions. It also activates the operator's creativity, since the operator starts questioning what he or she does out of habit.
3. Respect for the people: talk with courtesy, say hello and ask short questions focused on the Gemba itself.

You cannot see everything in one visit, so the material suggests starting with a few points:

• Order and cleanliness (5S): that the workstations have had everything unnecessary removed, that materials and tools have a known location, and that safety conditions are met.
• Material flow: the right quantity for the process, material piled up at workstations or between them, excess on shelves or intermediate inventories, and the reason for each accumulation.
• Information boards: up to date, with targets and indicators known to everyone, and with work instructions, quality controls and check sheets at each workstation.
• Equipment maintenance: current check sheets and maintenance standards, clean machines, no leaks.
• Offices and common areas, "sometimes the big forgotten ones."

The walk depends on who does it. The plant manager looks for waste and work standards, asks why things are done that way and tries to get to the root cause; the supervisor or shop foreman focuses on his or her own area, talks with the team, looks for improvements and makes sure the area is always in good condition. And the material stresses discipline: the more consistent the walks, the better the results. After walking the Gemba, hold a meeting with everyone who took part, to share the list of points to work on and who is responsible for each.

Real example

A made-up illustration from maintenance, using the points in the material to build the route: a maintenance manager walks the line every week with a list of five checks, one of them leaks and the equipment check sheets. Instead of reviewing the indicator dashboard from the office, the manager sees that a conveyor's lubrication sheet has not been filled in for days and that product is piling up before that workstation. The question "why?" leads to a concrete cause (no access to the grease point) and not to an opinion.

How to set it up

What I look at	What I found (facts)	Why it happens	Owner and date
Order and cleanliness (5S)
Material flow and accumulations
Boards and indicators in plain view
Equipment condition: leaks, cleanliness, check sheets
Offices and common areas

After the walk, the rows with findings go into an A3 report or an action plan with an owner and a date.

Benefits

• Decisions rest on observed facts and not on secondhand reports.
• It brings management closer to the people who do the work and shows respect for them.
• It quickly detects what does not show up in the indicators: accumulations, leaks, outdated instructions.

Limitations to keep in mind

• Without follow-up (a task list, owners and dates), the walk stays a courtesy visit.
• Asking "why" can feel like an inspection; the material insists on respect and on short questions.
• A single visit shows one moment: repeat it with discipline and on different shifts.

In summary

Gemba is the place of facts and Genchi Genbutsu is the habit of going to see them. A regular walk with three rules (go and see, ask why, respect the people), a list of points to look at and a closing meeting with owners is one of the simplest and most powerful tools of continuous improvement.
