Push principle
Manage production and replenishment based on forecasted demand, inventory standards, and a predefined schedule.
The push principle is a management approach where production and supply take place based on forecasted demand and a predetermined schedule. The approach is closely linked to the development of mass production and was later supported by material requirements planning, such as MRP. Unlike the pull principle, the consumption signal from the next process step is not leading; rather, the planned requirement is.
In production and logistics, the push principle is used, for example, to build seasonal stock, order materials with long lead times in good time, or plan production capacity in advance. Orders and materials are released according to the schedule, without each subsequent process step requesting them first. Proper implementation requires reliable forecasts, up-to-date inventory data, and realistic assumptions about capacity and lead times. In practice, push and pull are often combined: planning ahead where necessary and replenishing based on actual consumption where possible.
When applied well, the push principle helps ensure products are available when customers need them and enables the systematic deployment of people and machines. Furthermore, production in larger batches can reduce changeover and production costs per unit. However, when actual demand deviates from the plan, excess inventory, shortages, or bottlenecks can arise. The outcome therefore depends on the quality of the planning and the speed with which you adjust: not producing as much as possible, but keeping inventory, capacity, and customer demand in balance.
What is Push principle?
With the push principle, production and goods flows are initiated based on a schedule, without each subsequent process step first issuing a consumption signal.
When do you use it?
Applicable for predictable demand, long lead times, or larger batch production. Reliable forecasts and alignment between inventory, capacity, and sales are essential.
What are the benefits?
A sound push approach supports availability and capacity utilization. Conversely, incorrect assumptions can lead to excess inventory, additional work-in-progress, and longer lead times.
