The Art of Demand Management: Pull, Push, and Postponement Strategies in SCM

By?Rafael Vela ?/ Jun 16, 2023

Supply Chain Management (SCM) involves the coordination of various activities and processes to ensure the smooth flow of products or services from suppliers to customers. In this complex landscape, different strategies are employed to manage inventory, respond to customer demands, and optimize overall supply chain performance.

Among these strategies, Pull, Push, and Postponement play a significant role in shaping SCM practices and delivering value to customers. Let's explore these strategies in detail and understand their implications.

PULL STRATEGY

A Pull strategy, also known as a demand-driven strategy, focuses on fulfilling customer demand through real-time order information. In this approach, companies wait for customer orders before initiating production or distribution activities. The entire supply chain, including suppliers, manufacturers, and distributors, is synchronized to respond promptly to customer demands.

The key advantage of the Pull strategy is that it minimizes the risk of overproduction and excess inventory. By aligning production and distribution with actual demand, companies can reduce carrying costs, optimize inventory levels, and improve cash flow. Moreover, this customer-centric approach enables better customer satisfaction by ensuring timely order fulfillment and minimizing stockouts.

An example of a Pull strategy in the manufacturing industry can be observed in the automotive sector, an industry in which I worked for several years. Consider a car manufacturing company that implements a Just-in-Time (JIT) production system.

In this scenario, the car manufacturer collaborates closely with its suppliers to establish a Pull-based supply chain. Instead of producing cars based on sales forecasts or pushing products downstream, the company initiates the manufacturing process based on customer orders or actual demand.

When a customer places an order for a specific car model and configuration, the manufacturer starts the production process by pulling the necessary components and materials from its suppliers. The production of each vehicle is triggered by the actual customer demand, eliminating the need for excess inventory, and reducing the risk of overproduction.

By adopting a Pull strategy, the car manufacturer can achieve several benefits. Firstly, it minimizes inventory holding costs by producing only what is needed when it is needed. Secondly, it reduces the risk of obsolete inventory as cars are built based on customer orders, reducing the likelihood of unsold or outdated models. Thirdly, the Pull strategy improves production flexibility and enables customization, allowing customers to choose specific features and options for their vehicles.

The Pull strategy in the automotive industry, especially through JIT production, enables manufacturers to optimize their supply chain efficiency, reduce costs, and enhance customer satisfaction. By aligning production with actual customer demand, companies can improve inventory management, minimize waste, and deliver vehicles tailored to individual customer preferences.

Best Practices in Pull Strategy

When implementing a Pull strategy in supply chain management, there are several common best practices that can contribute to its effectiveness. These best practices include:

1. Accurate demand forecasting: Utilize data analysis, historical sales data, market trends, and customer insights to accurately forecast customer demand. This helps ensure that production and inventory levels are aligned with actual demand.
2. Collaborative relationships with suppliers: Establish strong partnerships and communication channels with suppliers to share demand information, coordinate production schedules, and enable timely delivery of materials and components. Collaboration helps minimize lead times and enhances responsiveness.
3. Efficient inventory management: Implement effective inventory management practices, such as just-in-time (JIT) principles, to minimize inventory holding costs and reduce the risk of obsolete or excess inventory. Regularly monitor inventory levels, analyze demand patterns, and optimize reorder points to maintain lean inventory levels.
4. Responsive production processes: Design production processes that can quickly respond to customer orders and demand fluctuations. Flexibility in manufacturing allows for rapid production ramp-up or downscaling based on actual customer requirements.
5. Continuous improvement and agility: Embrace a culture of continuous improvement and agility within the organization. Regularly review and refine processes, identify bottlenecks, and seek opportunities for optimization. This helps maintain responsiveness to changing market dynamics and customer demands.
6. Robust information systems and technology: Invest in robust information systems and technology infrastructure that can support real-time data sharing, demand visibility, and collaboration across the supply chain. Integrated systems enable accurate demand forecasting, timely order processing, and efficient inventory management.
7. Customer-centric approach: Place the customer at the center of decision-making and align supply chain operations to meet their specific needs. Focus on delivering superior customer service, timely order fulfillment, and personalized experiences.
8. Performance measurement and monitoring: Establish key performance indicators (KPIs) to measure and monitor the effectiveness of the Pull strategy. Track metrics such as customer fill rate, order cycle time, inventory turnover, and on-time delivery to identify areas for improvement and ensure continuous optimization.

By following these best practices, organizations can enhance the effectiveness of their Pull strategy and create a responsive supply chain that is aligned with actual customer demand. These practices enable efficient inventory management, improved customer satisfaction, and overall supply chain performance.

PUSH STRATEGY

Contrary to the Pull strategy, a Push strategy relies on forecasted demand to drive production and distribution decisions. In a Push strategy, companies proactively manufacture, and stock products based on anticipated (expected) customer demand. Production schedules, inventory levels, and distribution activities are planned, often driven by sales forecasts or historical data.

The Push strategy is beneficial in scenarios where demand is relatively stable and predictable. By forecasting demand and proactively producing goods, companies can achieve economies of scale, optimize production efficiency, and reduce lead times. However, the Push strategy carries the risk of excess inventory if demand forecasts are inaccurate, leading to increased holding costs and potential obsolescence.

An example of a Push strategy in the automotive industry can be observed in the production of spare parts or components for vehicles. In this scenario, an automotive manufacturer produces spare parts or components in advance based on forecasted demand and historical data, not on the customer′s real demand. These parts are manufactured and stocked in warehouses or distribution centers, ready to be shipped to dealerships or repair shops when needed.

This strategy helps streamline the supply chain and minimize potential delays in obtaining spare parts. It allows for quicker response times in addressing customer needs for repairs, reducing downtime for vehicles, and improving customer satisfaction.

However, it's worth noting that there are challenges associated with the Push strategy for spare parts. If the forecasted demand is inaccurate or if there are changes in vehicle models, the manufacturer may face the risk of excess inventory or obsolescence. Thus, it is crucial to continuously monitor market demand and adjust production levels accordingly to avoid overstocking or waste.

Best Practices in Push Strategy

There are several common best practices that can contribute to its effectiveness. These best practices include:

Track metrics such as customer fill rate, order cycle time, inventory turnover, and on-time delivery to identify areas for improvement and ensure continuous optimization.

These practices enable efficient inventory management, improved customer satisfaction, and overall supply chain performance.

POSTPONEMENT STRATEGY

The Postponement strategy aims to strike a balance between the Pull and Push strategies. It involves delaying the final customization or assembly of products until customer orders are received. Instead of producing finished goods in advance, companies maintain a base inventory of standardized components or semi-finished products that can be quickly configured or customized based on specific customer requirements.

It allows companies to respond rapidly to customer demands while minimizing inventory costs. By postponing the final configuration or customization, companies can reduce the risk of excess inventory and obsolescence. Furthermore, the Postponement strategy enables customization at the last possible moment, providing customers with more tailored solutions and reducing lead times.

An example of a Postponement strategy in the automotive industry can be seen in the customization of vehicle paint colors. Automotive manufacturers often offer a range of paint options for customers to choose from when purchasing a vehicle. Instead of applying the final coat of paint during the initial production stages, the manufacturer may postpone the painting process until the customer's desired color is confirmed.

Here the vehicles are assembled with a standardized base color, typically a neutral shade. Once a customer places an order with their preferred color or combination of colors, the manufacturer customizes the vehicle by applying the final coat of paint in the specified color. This postponement allows for greater flexibility and customization, as the manufacturer can accommodate individual customer preferences without the need for an excessive inventory of pre-painted vehicles.

This strategy reduces the need for maintaining a large inventory of vehicles in various paint colors, thus minimizing storage costs and the risk of obsolescence. It also enables quicker response times to customer orders, as vehicles can be painted in the desired color closer to the delivery date and it provides customers with the opportunity to choose from a wider range of paint options, enhancing their overall satisfaction and perceived value.

This strategy allows for efficient customization without sacrificing production efficiency or incurring excess costs associated with producing and storing pre-painted vehicles.

Best Practices in Postponement

When implementing a Postponement strategy in supply chain management, there are best practices that can contribute to its effectiveness. These best practices include:

1. Modular product design: Design products in a modular way, separating standardized components from customizable elements. This allows for easy customization or configuration of products based on specific customer requirements, without the need for significant changes to the core components.
2. Flexible manufacturing processes: Implement flexible manufacturing processes that can accommodate late-stage customization or configuration. Design production lines and assembly stations that can quickly adapt to different product variations and configurations, enabling rapid customization without disrupting the overall production flow.
3. Standardized base inventory: Maintain a standardized base inventory of components or semi-finished products that can be easily customized or configured as per customer demands. This base inventory acts as a flexible platform on which customization can be performed quickly and efficiently.
4. Demand-driven customization: Postpone the final customization or configuration of products until customer orders are received. This allows for customization based on actual customer requirements, reducing the risk of excess inventory and obsolescence. Align production and customization activities with specific customer demands to optimize responsiveness.
5. Efficient supply chain coordination: Collaborate closely with suppliers, manufacturers, and distributors to ensure smooth coordination of activities. Maintain strong communication channels to exchange real-time demand information and facilitate timely delivery of customized components or products.
6. Agile logistics and distribution: Implement agile logistics and distribution processes that can quickly respond to customized product orders. Optimize transportation routes, distribution centers, and delivery networks to minimize lead times and ensure timely delivery of customized products to customers.
7. Robust information systems: Invest in robust information systems and technology infrastructure to support real-time data sharing and visibility across the supply chain. Implement systems that enable accurate demand forecasting, order management, and customization tracking, ensuring efficient coordination and timely customization.
8. Continuous improvement: Foster a culture of continuous improvement and innovation within the organization. Regularly review and refine processes, identify opportunities for customization optimization, and incorporate customer feedback to enhance the efficiency and effectiveness of the Postponement strategy.

This approach allows for customization while minimizing inventory costs and obsolescence risks. It improves customer satisfaction by delivering products tailored to specific requirements and reduces lead times through efficient coordination and flexible manufacturing processes. Continuous improvement ensures ongoing optimization of the Postponement strategy, leading to increased operational efficiency and competitive advantage.

Choosing the Right Strategy

The choice of strategy depends on various factors such as product characteristics, demand patterns, market dynamics, and competitive landscape. Some products may be better suited for a Pull strategy, especially those with high demand variability or short product lifecycles. Others may benefit from a Push strategy, especially if demand is stable and predictable. In certain cases, a Postponement strategy can be advantageous, particularly when customization is required, or demand uncertainty exists.

Organizations must carefully evaluate their product portfolio, market dynamics, and customer preferences to determine the most suitable strategy or a combination of strategies. It is important to continuously monitor market conditions, customer demand patterns, and supply chain performance to make informed adjustments and ensure alignment with the chosen strategy.

The Pull, Push, and Postponement strategies in Supply Chain Management offer distinct approaches to managing customer demand, production, and inventory. Each strategy has its own benefits and considerations, and the choice depends on various factors specific to each organization. By carefully assessing product characteristics, demand patterns, and market dynamics, companies can leverage these strategies to optimize their supply chain operations, improve customer satisfaction, and achieve a competitive edge in today's dynamic business environment.
