The biggest lesson from our Lean simulation wasn't about production. It was about supervision.
Round 1: Drowning
In Round 1, the supervisor was drowning — transporting materials, answering questions, trying to be everywhere at once. Doing the work instead of managing the flow.
Round 3: Leading
By Round 3? They were sitting in the middle. Counting output. Watching for quality. Supporting the team. And the team delivered 14 products with zero defects.
One supervisor said afterwards:
"I need to stop acting straight away and start thinking about what's next and what's important."
That's the shift from operator to leader.

- Is the supervisor doing the work or managing the flow?
- Are they on the tools or counting the output?
- Are they firefighting or preventing fires?
The best supervisors I've seen don't touch a tool unless they have to. They keep the flow moving, remove blockers, and make sure quality is right before it moves on. That's not lazy. That's leadership.
