Factory games make invisible systems visible. Every belt, buffer, and stalled machine tells you something about the flow.
Bottlenecks are information
A backed-up belt is not merely a problem. It shows exactly where production and consumption disagree. Software teams often need the same kind of legible signal.

Speeding up one machine does nothing when the next stage is already full. The lesson travels well: optimize the whole path, not the easiest number to improve.
