Logistics and Supply Chain: Understanding the differences and complementarities.

By Jean-Désiré GROGUHÉ Ph.D.

Logistics and supply chain management are two closely related activities in international trade. However, they do not refer to the same reality. The distinction between them is often misunderstood, as the boundary separating the two concepts is not always obvious, even to some professionals.

In this article, we will attempt to clarify this ambiguity by providing a clear definition of each concept, examining their respective objectives, and illustrating them with practical examples that will hopefully help our readers gain a better understanding.

Before discussing their respective definitions, it is important to note that logistics is one component of the supply chain. The supply chain encompasses a much broader scope and is based on a more strategic approach to managing a company’s flows and resources.

1- Definitions

   a)   Logistics

By definition, logistics refers to all operations involved in planning, moving, storing, and delivering goods from their point of origin to their point of consumption. Its purpose is to organize and optimize transportation, warehousing, and distribution activities.

The management of physical flows and product-related operations includes transportation, storage, material handling, order preparation, and distribution. In some cases, it also includes reverse logistics. (1)

     b)   Supply Chain

The supply chain, on the other hand, covers a much broader scope, encompassing all stages from raw material suppliers to the final customer. This comprehensive strategic vision connects all stakeholders, including raw material suppliers, manufacturing operations, production planning, supplier management, logistics activities (transportation, warehousing, and delivery), customs operations, distributors and retailers, as well as demand management involving product, information, documentation, and financial flows.

In other words, the supply chain is the integrated system that manages the flow of goods, information, and financial resources from suppliers to end customers.

2- Objectives and Practical Examples

     a)   Objectives:

The primary objective of logistics is to deliver the right product, to the right place, at the right time, and at the lowest possible cost. The objective of supply chain management, however, is to coordinate all stakeholders and activities in order to optimize costs, lead times, and customer satisfaction.

For example, a company that organizes the transportation of goods from its factory to retail stores is performing logistics activities. A company that selects suppliers, plans production, manages inventory, and organizes product delivery is managing its supply chain.

For a supply chain to operate efficiently, three major flows must move continuously without interruption:

1.   Physical Flow: Goods and products moving through ships, trucks, warehouses, and distribution centers.

2.   Information Flow: Purchase orders, invoices, shipment tracking data, inventory information, and sales forecasts.

3.   Financial Flow: Payments, letters of credit, insurance transactions, and other financial arrangements.

     b)   Practical Example:

Consider a Canadian company that manufactures and sells laptop computers through Best Buy stores. Its supply chain involves several stages, from sourcing raw materials to delivering the final product to consumers.

Step 1: Raw Material Sourcing

• Lithium for batteries is sourced from Santiago, (Chile).

• Electronic chips are manufactured in Taipei, (Taiwan).

• Aluminum used for the laptop casings comes from Quebec, (Canada).

  
  

Step 2: Manufacturing and Production

Once these components are available, they are shipped to an assembly plant located in Beijing, (China).

Step 3: International Transportation (Logistics)

The finished laptops are transported in maritime containers from the manufacturing facility in Beijing to the Port of Tianjin, (China). They are then loaded onto a CMA-CGM or MSC vessel and shipped to either the Port of Vancouver or the Port of Montreal in Canada.

Step 4: Distribution and Warehousing

The products are subsequently transported by truck or rail and stored in a distribution center in Toronto.

Step 5: Final Delivery

The laptops are finally delivered to Best Buy retail stores or directly to customers through trucking companies or parcel delivery services such as Canada Post or UPS.

     C) Why Supply Chain Management Matters ?

To better illustrate the importance of supply chain management, consider a disruption of the physical flow caused by a longshore workers’ strike that blocks operations at the Port of Vancouver, resulting in inventory shortages.

To manage this crisis, a supply chain professional would rely on available information flows to identify alternative transportation routes, such as rerouting shipments through the Port of Prince Rupert, the Port of Montreal, or even by air freight. The objective is to minimize delays and prevent customer dissatisfaction.

In summary, logistics enables the movement of goods, whereas supply chain management orchestrates all the resources, information, processes, and partners required to create and deliver value to the final customer.

Conclusion

While the terms “logistics” and “supply chain” are frequently used interchangeably, they represent two distinct but closely interconnected concepts. Together, they aim to achieve customer satisfaction while improving the organization’s overall strategic and operational performance.

In today’s environment of globalization, geopolitical uncertainty, logistical disruptions, and growing customer expectations, supply chain management has become a critical source of competitive advantage. Organizations that excel are those capable of seamlessly integrating their logistics activities into a broader supply chain strategy that anticipates risks, responds rapidly to market changes, and consistently delivers reliable and high-quality service to customers.

(1) Reverse logistics is the process of managing the flow of goods from the point of consumption back to the point of origin to recover value or ensure their proper handling, reuse, recycling, refurbishment, or compliant disposal (e.g., defective products, customer returns, the return of empty containers or pallets, recycling, etc.)
