Do you go to the Gemba… or do you go to a line-side show?

One of the most common pieces of Lean advice is: "Go to the Gemba."

Go where the work is done. Observe the process. Talk to the people doing the work.

I couldn't agree more. But in many large organizations, that's not what actually happens. Instead, top management announces a plant visit weeks in advance. Suddenly everyone is cleaning and painting, updating visual boards, making sure every machine is running, rehearsing presentations, preparing the "perfect" route through the plant. You name it.

By the time leadership arrives, they aren't seeing the operation. They're watching a performance.

That's not the Gemba. That's theater.

I've seen this firsthand more times than I can count. The intention is understandable. Every team wants to make a good impression.

But there's an unintended consequence: The very people who have the authority to remove barriers, allocate resources, and drive change never get to see the real problems.

Meanwhile, operators—the people who live with those problems every day—rarely get an opportunity to have an honest conversation.

If your quality, OEE, uptime, delivery, or safety metrics aren't where they need to be... What is the value of pretending everything is fine for one afternoon?

In fact, it often makes things worse. Problems stay hidden. Resources are allocated based on perception instead of reality. Opportunities for improvement are missed.

Real Gemba walks require more than comfortable shoes. They require curiosity, humility, and psychological safety. Go to the line. Talk to operators, technicians, maintenance, and supervisors. Ask questions instead of giving answers. Observe more than you speak. And if possible, visit without the fanfare.

One of the best signs of a healthy culture is when people feel comfortable telling leadership: "Here's what's really happening."

Because you can't improve what you never truly see.

So here's my question for manufacturing leaders:

When you visit the floor, are you seeing the operation... or are you watching a well-rehearsed show?
