Sometimes the right engineering decision looks completely wrong on paper.
One of our critical machines had already been out of service for months.
The worm gear had stripped.
It had been repaired.
Then it stripped again.
The gearbox had been removed, rebuilt and reinstalled, and we were finally ready to start putting the machine back into service.
Production wanted it running.
So did I.
But while I watched the contractors finishing the job, something didn't sit right.
Then, as they were preparing to leave, I was told:
“Just put the motor back on. It'll be fine.”
That was enough for me.
I stopped the recommissioning.
And at that point, I couldn't prove I was right.
I brought in a specialist with years of experience on these machines.
This was actually my first introduction to the man who would later become known to us simply as...
“The Wizard.”
His recommendation?
Take the gearbox back out.
It was sent away and completely stripped down again.
Then the phone call came.
The gearbox had been rebuilt incorrectly.
Had we started the machine, there was every chance we'd have damaged the worm gear again.
They also uncovered further problems with previous repairs.
The result?
Nearly another three months of downtime.
On paper, my decision had made performance worse.
But getting a machine running isn't the same as making it reliable.
We changed contractors after that.
Not because the replacement was cheaper or quicker.
Because we'd reached the point where competence and trust mattered more than either.
That experience changed the way I look at engineering decisions.
Sometimes leadership means resisting the pressure to restart something when you don't believe it's ready.
Another week of downtime is visible.
The failure you prevent isn't.
Reliability isn't defined by how quickly you're prepared to restart a machine.
Sometimes it's defined by whether you're prepared to keep it stopped.
And that was also the day I first met The Wizard.
He'll appear again in a few of these stories.
Have you ever made a decision that made the KPI worse in the short term because you knew it was right for the long term?
