Push Pull System in Supply Chain Management Explained
Understanding the Push-Pull System in Supply Chain Management
The push-pull system in supply chain management is a strategy used to manage the flow of goods and services. It combines two different approaches: the push system and the pull system. Each approach has its own strengths and weaknesses, and understanding them is crucial for businesses aiming to optimize their supply chain operations.
What is a Push System?
In a push system, products are manufactured based on forecasted demand. This means that companies produce goods in advance and push them through the supply chain to retailers or customers. The key characteristics of a push system include:
- Forecasting: Companies rely heavily on demand forecasts to determine how much to produce.
- Inventory Management: Finished goods are kept in inventory until sold.
- Production Scheduling: Production is scheduled based on anticipated demand rather than actual orders.
What is a Pull System?
In contrast, a pull system is driven by actual customer demand. Products are only made or ordered when there is a confirmed need from the customer. The main features of a pull system include:
- Demand-Driven: Production and inventory levels are based on real-time customer orders.
- Reduced Inventory: Less finished goods inventory is held, minimizing holding costs.
- Flexibility: Companies can quickly adapt to changes in customer preferences.
Why the Push-Pull System Matters
