Push vs Pull System in Job Shop Manufacturing

August 4, 2023 | Tips

Learn about push and pull supply chain management systems in job shop manufacturing

In the dynamic landscape of manufacturing management, two prominent approaches stand out: Push System and Pull System. Push systems produce goods based on forecasts of future demand, while pull systems produce goods only when there is an actual demand. These supply chain management strategies play a crucial role in shaping how production processes are organized and controlled. Understanding the differences between the two can empower manufacturers to make informed decisions that optimize productivity, minimize waste, and enhance overall operational efficiency. In this article, we’ll delve into their core concepts, explore their unique characteristics, and examine how they impact product availability and customization. Moreover, we’ll discuss how combining these systems can lead to synergistic outcomes.

What is a Push System

The Push System is a traditional production approach where goods are manufactured based on long-term forecasts and predetermined production schedules. In this system, production processes are initiated based on anticipated demand, regardless of the actual customer orders. Manufacturers forecast what they believe will sell in the market and push those products into the supply chain. Push systems can be effective in some cases, such as when demand is relatively stable and predictable. However, they can also lead to problems, such as:

1. Overproduction: If the forecasts are wrong, manufacturers may end up producing too much of a product, which can lead to waste and financial losses.
2. Excess inventory: Push systems can also lead to excess inventory, which can tie up capital and make it difficult to respond to changes in demand.
3. Poor quality: If products are produced before there is a demand for them, there is a greater risk that they will be of poor quality.

What is a Pull System

On the other hand, the Pull System is a lean manufacturing approach that operates on actual customer demand. In this system, products are pulled through the supply chain in response to customer orders or consumption. The focus is on producing items only when there is a genuine demand, avoiding unnecessary production and excessive inventory. Pull systems can be more effective than push systems in a number of ways, including:

1. Reduced inventory: Pull systems can help to reduce inventory levels, which can save money and improve efficiency.
2. Improved quality: Pull systems can help to improve quality, as products are only produced when there is a demand for them.
3. Better responsiveness to demand: Pull systems can help manufacturers to respond more quickly to changes in demand

Push System vs Pull System

Push and pull systems have different implications for product availability and customization. The first ones tend to lead to more product availability, as manufacturers are producing goods even when there is no current demand. However, this can also lead to excess inventory and waste. Pull systems, on the other hand, tend to lead to less product availability, as manufacturers are only producing goods when there is a customer order. However, this can also lead to better quality and a more responsive supply chain.

For example, a manufacturer of consumer electronics might use a push system to produce TVs. The manufacturer would forecast demand for TVs based on historical sales data and then produce a certain number of TVs each month. This would ensure that there are always TVs available for customers to purchase. However, if the forecast is wrong, the manufacturer could end up with excess inventory. On the other hand, a manufacturer of custom furniture might use a pull system. The manufacturer would only produce furniture when there is a customer order. This would ensure that the furniture is exactly what the customer wants, but it could also lead to delays in delivery.

In practice, most manufacturers use a hybrid system that combines elements of both push and pull systems. This can be a more effective approach than using either system exclusively. For example, a manufacturer of car parts might use a push system to produce common parts that have a stable demand. However, the manufacturer might use a pull system to produce more customized parts that have less predictable demand.
