why wire harness production schedules fall apart (and why it's not just capacity)
Wire harness production schedules have a way of looking reasonable right up until they don’t.
On Monday morning, the board makes sense. Jobs are lined up. Labor is assigned. Materials are expected. The team knows what needs to ship and when. By Wednesday, priorities have shifted, one job is waiting on connectors, another needs rework, a customer expedites a short-run order, and the schedule that looked solid two days ago is suddenly more suggestion than plan.
It’s easy to blame capacity. Not enough people. Not enough benches. Not enough hours in the week. Sometimes that’s true. But in many small and midsize wire harness shops, capacity is not the real scheduling problem. The deeper issue is the lack of live production reality.
You can’t schedule well if you can’t see what is actually happening.
