Same nine people. Same resources. Same ten minutes.

Round 1: Zero products delivered. Frustrated customer. Chaos everywhere.

Round 3: Fourteen delivered. On time. Zero defects. Team had time to spare.

What changed? Not the people. Not the budget. Not the hours. The process.

The Lean Car Game Simulation

We ran a Lean simulation in Adelaide — a factory-style car assembly game that mirrors what happens on every building site. In Round 1, everyone followed the "way we've always done it." Batch production. One material handler running back and forth. Operators waiting. Supervisor drowning.

Zero cars reached the customer.

What the Team Changed (Using Data)

Between rounds, the team made changes based on data — not gut feel:

• Moved stations closer together
• Eliminated the material handler bottleneck
• Put parts at each station (point of use)
• Split the slowest station into two people
• Focused on quality first, let speed follow

The Mind-Blowing Part

By Round 3, they had time left over. They could have slowed down, taken breaths, double-checked quality — and still met demand. That's what happens when you fix the process instead of yelling "go faster."
