A business owner I worked with once proudly showed me his production dashboard.
He said, “Shrikant, our machine utilization is above 90%. The factory is fully loaded.”
On paper, it sounded impressive.
Machines were running.
Operators were busy.
The shop floor looked active.
But there was one problem.
Delivery performance was still inconsistent.
Lead times were increasing.
And margins were under pressure.
So the question became:
If utilization is so high, why isn’t performance improving?
When we looked deeper, the answer became clear.
The business was measuring activity.
Not effectiveness.
And this is where machine utilization becomes misleading.
Because high utilization does not always mean high productivity.
In many factories, machines are running constantly—but not always on the right jobs, in the right sequence, or with the right efficiency.
For example, one company had machines running long hours, but frequent changeovers were quietly eating productive time.
Another had machines busy producing low-priority orders while urgent, high-margin jobs waited in queue.
And in some cases, machines stayed occupied simply because planning was poor and work-in-progress kept piling up.
The factory looked busy.
But output was not improving at the same pace.
This is the danger of focusing only on utilization percentages.
Because a machine running for ten hours is not automatically creating value for ten hours.
You have to ask deeper questions.
Are machines producing what customers actually need right now?
How much time is lost in setups, waiting, or rework?
Is higher utilization improving throughput—or simply increasing work-in-progress?
Sometimes, pushing for maximum utilization actually slows the system down.
Especially when bottlenecks become overloaded and production flow suffers.
The factories that perform well don’t only track whether machines are busy.
They track whether machines are helping the business deliver faster, more predictably, and more profitably.
The question worth asking is this:
In your factory, are machines truly productive?
Or are they simply staying busy while bigger problems remain hidden?
