Backward Chaining: Moving Upward The Supply Chain

Backward chaining, also called backward integration, describes a process where a company expands to fulfill roles previously held by other businesses further up the supply chain. It is a form of vertical integration where a company owns or controls its suppliers, distributors, or retail locations.

Aspect	Explanation
Definition	Backward Chaining in Supply Chain is a logistics and planning approach that starts with the final customer demand and works backward through the supply chain network to determine the necessary steps, processes, and resources required to meet that demand. It helps organizations optimize their supply chain operations by aligning them with customer demand, improving efficiency, and reducing unnecessary inventory and costs.
Process	– Customer Demand: The process begins with an understanding of customer demand, which can include orders, sales forecasts, or historical data. This represents the ultimate goal or endpoint of the supply chain. – Working Backward: Starting with customer demand, organizations analyze the various stages of their supply chain in reverse order, moving from distribution and transportation back through manufacturing, production, and raw materials or components sourcing. – Resource Allocation: At each stage of the backward chain, decisions are made regarding resource allocation, production schedules, inventory levels, and transportation routes based on the demand and constraints. – Efficiency Improvement: By identifying the critical path and optimizing processes, organizations can streamline their supply chain operations, reduce lead times, minimize inventory holding costs, and ensure on-time delivery to customers.
Applications	– Backward Chaining in Supply Chain is widely used in industries such as manufacturing, retail, and distribution. It is especially valuable in industries with complex and global supply chains, where understanding and aligning with customer demand are paramount. – In e-commerce, for example, companies use backward chaining to efficiently manage inventory, fulfillment, and delivery processes to meet customer expectations for quick and accurate deliveries.
Advantages	– Customer-Centric: It aligns supply chain operations with customer demand, ensuring that products or services are available when and where customers need them. – Cost Reduction: By optimizing processes and minimizing excess inventory, organizations can reduce carrying costs, warehousing expenses, and transportation expenses. – Efficiency: It improves supply chain efficiency by eliminating bottlenecks, reducing lead times, and enhancing overall operational performance.
Limitations	– Data and Forecasting Challenges: Accurate customer demand forecasting and data availability are essential for effective backward chaining. Inaccurate data or unreliable forecasts can lead to suboptimal decisions. – Complexity: Managing a complex supply chain network with multiple stages, suppliers, and distribution channels can be challenging and require sophisticated planning and optimization tools. – Response to Dynamic Demand: Adapting the supply chain in real-time to dynamic shifts in customer demand can be difficult and may require agile supply chain strategies.
Real-World Example	An example of backward chaining in supply chain management is a company that manufactures consumer electronics. Starting with customer orders and sales forecasts, it works backward through its supply chain, determining production schedules, inventory levels, and sourcing strategies for raw materials and components. This approach ensures that the right products are available in the right quantities at the right time to meet customer demand.

Understanding backward chaining

Supply chains start with the sourcing of raw materials. These materials are then delivered to a warehouse or factory and then into stores for purchase by consumers.

The supply of raw materials is sometimes unpredictable and in short supply. As a result, these resources are highly prized and there is much competition among organizations in trying to secure them. Businesses use backward chaining to shore up these resources for themselves, eliminating all competition in the process.

Backward chaining is also a highly effective competitive strategy. With more control over its supply chain, a business decreases costs and eliminates potential supply chain pressures.

Advantages

Efficiency. With greater control, businesses can streamline every aspect of the supply chain to suit their needs and preferences. The efficiency of backward chaining might reduce transportation costs and improve profit margins. In a retail context, a business with total control over its supply chain is better able to stand behind the availability of its products.
Reduced costs. Traditional supply chains consist of one or more middlemen who charge a mark-up for their services. With the middleman removed, acquiring raw materials becomes cheaper and these savings can be passed to the consumer.
Intellectual property acquisition. For example, backward chaining in the technology industry might see a business gain exclusive rights to trademarks, patents, and other proprietary information owned by their former suppliers.

Disadvantages

Cost. Backward chaining requires a substantial investment that not all businesses will be able to absorb.
Reduced economies of scale. Normally, a supplier who supplies multiple businesses may pass on savings resulting from economies of scale. Since backward chaining reduces the number of individual units being produced, the company acquiring the supplier might face higher production costs.
Manageability. Companies that acquire entire supply chains might become large and more troublesome to manage. Spread so widely, there core strengths and values may also become diluted.

Examples of backward chaining

Netflix started out as a DVD rental company with a focus on television and film. Eventually, the company employed backward chaining to acquire the rights to start making content themselves.

Ford Motor Company originally sourced key raw materials such as rubber, glass, and metal from suppliers. In order to protect its supply, Ford created several subsidiaries to control the supply of these materials, guaranteeing availability, and increasing quality.

Apple is also a proponent of backward chaining. Apple software is installed on electronic devices and operating systems that are owned by the company. Hardware and manufacturing facilities are also under-owned by the tech giant.

Key takeaways:

Backward chaining is the process of a company acquiring other companies further up the supply chain, ostensibly to secure raw materials.
Backward chaining is an effective competitive strategy because it increases efficiency and reduces costs. However, it does require large amounts of capital and has the potential to dilute a company’s brand.
Backward chaining is common to many of the world’s largest and most successful companies.

Key Highlights

Definition and Origin: Backward chaining, also known as backward integration, is a form of vertical integration where a company expands its operations to include roles previously held by other businesses up the supply chain. It involves owning or controlling suppliers, distributors, or retail locations.
Supply Chain Control: Backward chaining allows a company to gain control over its supply chain, starting from raw material sourcing. This strategy is particularly useful when raw materials are scarce or unpredictable, as it secures resources and eliminates competition for them.
Advantages:
- Efficiency: By streamlining the supply chain to align with the company’s needs, efficiency can improve, reducing transportation costs and ensuring product availability.
- Reduced Costs: Cutting out middlemen in the supply chain lowers costs, allowing savings to be passed on to consumers.
- Intellectual Property: Through backward chaining, a company can acquire exclusive rights to trademarks, patents, and other proprietary information owned by suppliers.
Disadvantages:
- Cost: Implementing backward chaining requires a significant investment that might not be feasible for all businesses.
- Economies of Scale: Reducing the number of units produced due to backward chaining might lead to higher production costs, losing out on economies of scale.
- Manageability: Expanding across the supply chain can lead to challenges in managing a larger and more diversified business.
Examples:
- Netflix: Started as a DVD rental company and later used backward chaining to produce its own content.
- Ford Motor Company: Created subsidiaries to control the supply of raw materials like rubber, glass, and metal to ensure quality and availability.
- Apple: Owns hardware, manufacturing facilities, and software components to maintain control over its products and services.
