Your plant is full of improvement projects. Almost none of them will move your output. Here's the uncomfortable math. Your total throughput is set by one constraint. One station, one machine, one step that everything else has to pass through. Improve anything upstream or downstream of it, and you have not added a single unit of output. You've just built more inventory and made a station look busier. This is why "keep everyone busy" is one of the most expensive habits in manufacturing. A machine running flat out, feeding a constraint that can't keep up, isn't being productive. It's just building a bigger pile the bottleneck can't get through. And the operators who look underutilized upstream? They aren't slacking. They're correctly waiting on the one thing that actually sets the pace. The whole game is to find that one constraint, throw everything at it, and leave the rest alone until it moves. But here's the catch a lot of plants hit. They can't agree on where the constraint even is. Everyone points at a different station, so effort gets sprinkled everywhere, and nothing moves. You can't fix a constraint you can't see. So before you greenlight another improvement project, find the one place work actually piles up. That's not your slowest team. That's your constraint. Have you found yours, or are you still improving everywhere?
