I used to build apartment blocks. I had 37 carpenters. And one number from those years has stuck in my head ever since — because it exposes a lie that costs business owners millions, every single day, without them ever noticing.

They were good. Not "good for the price." Good. On an average day, each man produced 40 square meters of formwork — columns, beams, floors. Consistently. Week after week, the numbers landed where they were supposed to land. I was on site twelve to sixteen hours a day, seven days a week, and I knew every one of those men by name, by habit, by how they took their coffee.

Eventually I hit a wall. My body was done. I stepped away from construction. The crews still needed work, so I did them a favor — I sent them to a friend building the same kind of blocks. Same city. Same buildings. Same tools. Same men.

A few weeks later, he called me.

"Your guys are doing 8 square meters a day."

Not 40. Not 30. Eight.

Same hands that built my towers. Five times less output. And here's where most people get it catastrophically wrong: my friend assumed the problem was the men. He started muttering about lazy workers, about how "you can't find good people anymore," about firing them and bringing in a new crew.

He was about to fire the best carpenters in the city. Because nobody told him the truth.

The men hadn't changed. Not their skill, not their tools, not their work ethic. The system around them had changed. No clear targets. No one tracking real output. No accountability that connected effort to result. Drop a Ferrari engine into a car with the handbrake on and you'll swear the engine is broken.

The team is never the variable. The system around them is.

I carried that 40-to-8 ratio into every business I ran after that — pest control, facility management, logistics, food, automotive. And every time someone complained about "bad employees," I'd find the same thing underneath: a good worker, strangled by a system nobody was measuring.

Here's the part that should make you uncomfortable. Most owners look at underperformance and reach for the easy answer — wrong people. So they hire, fire, replace, repeat. New faces, same numbers. They burn through good workers and good money, and they never once look at the actual machine those people are trapped inside.

Because looking at the machine means measuring things nobody wants to measure. Not hours worked — hours that actually produced something. Not what payroll says the team costs — what the team really costs when you add the overhead, the support staff, the equipment, the people who exist only to keep the productive ones running. Not whether the project got finished — whether it got finished profitably.

When you can finally see those numbers, you stop blaming people and start fixing the thing that's actually broken. And the difference isn't 10 percent, or 20. My carpenters proved it can be 500.

The most expensive problem in business isn't a bad employee. It's a good employee in a broken system — and an owner who can't tell the difference.
