Lean manufacturing has a concept called the gemba walk.

Gemba is Japanese for "the real place." The place where value is actually created; the shop floor, the point of sale, the patient check-in desk, the loading dock.

The idea is simple. If you want to understand how work actually happens, you have to go see it. Not read a report about it. Not sit through a presentation about it. Go see it.

Technology leaders need to adopt this discipline. Not as a visit. As a practice.

And when you go, do the work

Do not observe, participate.

If you work for a fast food chain, ring up customers, place resupply orders, close out the register at the end of a shift. If you work for a retailer, work the floor during peak hours. If you work for a distribution company, pull an order and walk it through the warehouse.

You will learn more in four hours of doing the work than in four months of reviewing dashboards.

Because the system your team built, and the system people actually use, are often two very different things.

I learned this the hard way

Earlier in my career, at a large medical group, we had a credit card processing system that finance loved.

And they had good reasons to love it. Reconciliation time dropped by an hour every day compared to the old solution. It was integrated with their preferred banking partner. For the people managing the books, it was a clear improvement.

So that was the system we used, finance signed off, it worked well for us. We thought.

Then I went into the field and actually checked out patients after their visits.

Here is what I found.

After every appointment, I had to manually copy the patient's name and the amount due from the electronic medical record into a completely separate, disconnected credit card application. Run the transaction. Then manually record that the transaction was completed. Back in the first system.

Every checkout took over a minute. With the patient standing there waiting.

And it got worse. In every clinic, the office manager was spending about 30 minutes every day reconciling payments with the EMR. Because when it was busy, mistakes were made. Manual entry creates errors. Errors create reconciliation work. That work was invisible to everyone except the people doing it.

Finance was saving an hour a day at the company level. And we were burning 30 minutes a day per clinic, plus damaging the patient experience at every single checkout.

Nobody knew, because nobody had gone to see.

We fixed it

We switched to an integrated solution where the payment processed directly from within the EMR. One system, no manual copying, no disconnected applications.

The results were straightforward.

Checkout time dropped significantly, patients noticed, the experience improved immediately.

Each clinic saved 30 minutes a day on reconciliation. Across many locations, that adds up fast.

And yes, finance gave back an hour. Their reconciliation process got a little harder. That was a real tradeoff, and it was the right one, because the work was happening where the patients were, not in a back-office accounting workflow.

I would not have understood any of this without going into the field. The data did not show it. The reports did not show it. The stakeholder meetings did not show it.

The checkout desk showed it.

The lesson is not about credit card systems

The lesson is about where insight actually comes from.

As technology leaders, we are in the business of making work better for the people doing it. Not just faster on paper. Not just cleaner in a report. Better for the person doing the work, and better for the customer on the other side of it.

You cannot design that from a conference room.

Go to the gemba. Do the work. Watch where people hesitate, where they work around the system, where they apologize to the customer because the technology is slowing them down.

That is where the real problems live. And that is where the real improvements come from.

The best technology decisions I have ever made started with me doing a job I was not hired to do.

Go see the real place.
