Pull vs Push Scheduling: Make to Signal vs Make to Forecast

Pull vs Push Scheduling: Make to Signal vs Make to Forecast

Push schedules production from a forecast and an MRP plan. Pull triggers production from real downstream demand. The choice shapes inventory, WIP, and responsiveness.

Key takeaways

  • Push schedules work from a forecast and an MRP plan, regardless of actual consumption.
  • Pull triggers production only when downstream demand signals a need.
  • Push risks overproduction and excess WIP; pull risks stockout if signals or buffers are wrong.
  • Most real plants run a hybrid — push at the plan level, pull at execution.

Short answer: Push scheduling releases work based on a forecast and MRP — make it because the plan says so. Pull releases work only when downstream demand consumes something — make it because it was used. Push tends to overproduce and build WIP; pull keeps inventory low but needs reliable signals and buffers. Most plants blend the two. See also oee for manufacturing.

How push works

  • Forecast drives the MRP plan.
  • Work released to schedule, not consumption.
  • Good for stable, long-lead, forecastable demand.

How pull works

  • Downstream consumption signals replenishment.
  • Kanban or CONWIP caps WIP.
  • Good for repetitive, steady demand.

The trade-offs

Push amplifies forecast error into excess inventory and the bullwhip effect. Pull minimises inventory but stalls if buffers are mis-sized or demand spikes beyond them. Neither is universally right.

The hybrid most plants run

Push for planning and long-lead procurement; pull for shop-floor execution and replenishment. The plan sets the envelope; consumption sets the pace inside it.

How OEE relates

Pull smooths flow and reduces the starve-and-block that hurts OEE Performance. Push can keep a bottleneck fed but at the cost of WIP and the losses it hides.

Frequently asked questions

Is pull always better?

No — push suits forecastable, long-lead demand.

Is MRP push or pull?

MRP is push — it plans from forecast.

Can I combine them?

Yes — hybrid push-plan, pull-execute is common.

How does pull help OEE?

It reduces starving and blocking that cause Performance loss.
