Fixing a Run-Down Machine Isn't Enough

When I took over maintenance at a struggling facility some years ago, I found a machine rated at 14,000 units per hour running at 10,000.

I did the math. At $0.60 spread per unit, that gap was worth $2,400 per hour in recoverable value (throughput accounting).

I made promises. I found the money. I fixed the machine.

The next week, it ran at 10,000 units per hour.  No improvement.

The operators told me the machine just couldn't go faster. The material wouldn't allow it.

That's just how it ran. And they believed it, because for them, it was true.

I feared I might be fired.  I had made big promises for a payback and fixing the machine didn't deliver it.

Then we brought in a trainer. The press ran at 14,000 within hours... and continued to do so for the rest of the time I was at that facility.

Here's what I had wrong:

I thought deferred maintenance was the problem.  Fix the machine and performance will rebound.

But deferred maintenance is also a process problem.

Every time something broke and didn't get fixed, operators adapted. They slowed the machine. They changed the setup. They abandoned non-functional systems. They found workarounds.

Those workarounds got passed down. They became training. They became standard.  They became tribal knowledge.

By the time I arrived, "running the press" meant running a corrupted version of the process, built around broken equipment, that nobody recognized as corrupted because it was all anyone had ever known.

Fixing the equipment removed the constraint, but the process was still broken. The knowledge of how to run it correctly had been quietly written out of the organization over years of deferred maintenance and acceptable decline.

This is the hidden cost nobody calculates:

Deferred maintenance doesn't just damage equipment.  It rewrites your processes, one adaptation at a time, until the degraded state becomes the standard.

And most facilities don't have enough process control to detect that drift, let alone reverse it.

It's imperative for plants to maintain equipment to standard to avoid this process corruption because it takes a concerted effort to defeat it once you're there.

When a turnaround leader shows up, fixes the equipment, and wonders why performance doesn't follow, this is why.

You can't turnaround a facility by fixing equipment alone.

You have to fix the equipment and recover the process. And to recover the process, you need to have enough process control infrastructure to know what the original standard even was.

And your experts are corrupted.  You have to get outside experts to fix the process.

If you don't have control to that degree, and most facilities in distress don't, you're not getting a turnaround.

The real question for every plant manager:

If your equipment returned to full spec tomorrow, would your operators know how to run it?

Or has the degraded process already become the only process they know?
