What is Logistics? What is Supply Chain?

Let’s start with the basics.

  • Logistics: Logistics refers to the process of planning, implementing, and controlling the movement and storage of goods, services, and information from their point of origin to their intended destination. It involves activities such as procurement, transportation, warehousing, inventory management, and distribution. Essentially, logistics ensures that the right goods are in the right place at the right time, while minimizing costs and maximizing efficiency throughout the supply chain.
  • Supply Chain: Supply chain, on the other hand, refers to the network of organizations, resources, activities, and technologies involved in the creation and delivery of a product or service to the end customer. It encompasses all stages of the product lifecycle, from raw material sourcing and production to distribution and retail. The supply chain involves coordination and collaboration among various stakeholders, including suppliers, manufacturers, distributors, retailers, and customers, to meet customer demand effectively and efficiently.

The Journey Begins: Sourcing and Procurement

1. Sourcing:

  • Companies source raw materials and components globally, focusing on quality, cost, and reliability.
  • The sourcing process involves evaluating factors like quality, cost, reliability, and lead times.
  • Supplier audits, site visits, and performance assessments ensure alignment with company standards.
  • Negotiations establish mutually beneficial terms covering pricing, payment, delivery, and quality.
  • Some examples of raw materials that must be sourced include metal, plastic, and minerals.  
  • The goal is to secure favorable terms while maintaining sustainable supplier relationships.

2. Procurement:

  • Procurement teams negotiate contracts, place orders, and manage supplier relationships.
  • They execute agreements from the sourcing stage, issuing purchase orders and managing contracts.
  • Effective procurement requires monitoring inventory, demand, and production schedules.
  • Teams balance maintaining adequate inventory with avoiding excess stock.
  • Supplier relationships are managed through communication, performance reviews, and feedback sessions.

Setting the Foundation

Overall, the sourcing and procurement stage sets the foundation for a successful supply chain operation. It does this by establishing reliable supplier relationships and securing the necessary materials and components to drive production and meet customer demand. It requires strategic planning, effective negotiation, and diligent execution to optimize value and maintain competitiveness in the marketplace.

Example: Apple Inc.

Apple is known for its robust sourcing and procurement. By establishing strong and long lasting relationships with their suppliers, Apple is able to ensure the electronic parts they receive are consistently high quality. Along with that, Apple has a large and diversified supplier base. This is to ensure that they are not overly dependent on one supplier in case of a supply chain emergency. It also gives them more bargaining leverage when negotiating deals with their suppliers.    

From Factory to Shelf: Production and Manufacturing

The transition from factory to shelf involves the critical stage of production and manufacturing, where raw materials are transformed into finished products ready for distribution and consumption. This phase is characterized by a series of carefully orchestrated processes and assembly lines aimed at achieving efficiency, consistency, and quality in product output.

Production Process:

  • The production process begins with the receipt and inspection of raw materials and components sourced during the procurement phase.
  • Materials are processed, manipulated, or assembled according to predetermined specifications and design requirements.
  • Techniques such as machining, molding, casting, welding, or assembly are employed, depending on the product’s nature.

Efficiency is paramount during the production phase, as companies strive to optimize resource utilization, minimize waste, and maximize output. Lean manufacturing principles and continuous improvement methodologies are often employed to streamline operations, reduce cycle times, and enhance productivity. Practices such as Just-In-Time (JIT) manufacturing, Total Quality Management (TQM), and Six Sigma are utilized to eliminate defects, improve process efficiency, and enhance overall performance.

Transforming the Product

The production and manufacturing phase is a critical component of the supply chain, where raw materials are transformed into finished products through a series of processes and assembly lines. Efficiency, quality, cost management, capacity planning, and continuous improvement are key considerations that drive success in production operations and contribute to overall supply chain performance and competitiveness.

Example: Ford and Volkswagen.

A famous example of this is when Ford introduced the idea of the assembly line for the Model T. The assembly line increased efficiency immensely, allowing raw materials to be turned into products on a massive scale. Volkswagen improved on this further by implementing just-in-time manufacturing that is complimented by a technologically advanced assembly line. By having a rail line that feeds directly to the factory, Volkswagen is able to ensure that parts arrive quickly and completed cars leave just as fast. They also have a cutting edge system of sensors, cameras, and detectors that are able to spot defective machines before they completely break down. This allows them to quickly swap out entire machines in minutes so the production line virtually never has to shut down for repairs.  

On the Move: Transportation and Distribution

The phase of transportation and distribution is a pivotal stage in the supply chain, where products move from manufacturing facilities to distribution centers or directly to retailers and consumers. This stage involves two primary components: transportation and distribution.

1. Transportation:

Transportation is the process of moving goods from one location to another, typically from manufacturing facilities to distribution centers, retail stores, or directly to consumers.

Various modes of transportation, including trucks, trains, ships, and planes, are utilized based on factors such as distance, urgency, cost, and the nature of the goods being transported.

Transportation logistics play a crucial role in ensuring the timely and efficient movement of goods. This involves planning and coordinating transportation routes, scheduling shipments, selecting carriers, and managing transportation assets.

Efficient transportation logistics help goods reach their destination on time and intact, facilitating smooth operations and meeting customer expectations. Factors such as tracking and tracing capabilities, freight visibility, and real-time communication with carriers are essential for monitoring shipment progress and addressing any issues or delays that may arise during transit.

2. Distribution:

  • Distribution involves the sorting, storing, and preparation of products for shipment to retailers or directly to customers.
  • Distribution centers serve as hubs where products are received from manufacturing facilities, consolidated, and then redistributed to various destinations.
  • Products undergo processes such as sorting, labeling, packaging, and quality control checks at distribution centers to ensure they are ready for shipment.

The distribution process requires careful coordination to ensure that the right products are in the right place at the right time. Effective distribution logistics are critical for maintaining supply chain efficiency, reducing order fulfillment times, and meeting customer service level agreements.

Moving the Product

Transportation and distribution logistics are integral components of the supply chain, responsible for ensuring the efficient movement of goods from manufacturing facilities to distribution centers and ultimately to end customers. By optimizing transportation routes, selecting the appropriate transportation modes, and implementing efficient distribution processes, companies can enhance supply chain performance, reduce costs, and improve customer satisfaction.

Example: Goya Foods.

An example of transportation and distribution perfected is Goya Foods. Goya Foods receives thousands of orders every day from all over the country. To effectively handle this, Goya has implemented a robust transportation and supply system. This includes daily orders that are submitted by salespeople which are then sent to the closest Goya owned warehouse. Each Goya owned warehouse is equipped with extra tall and space saving shelving as well as state of the art forklifts to handle the tall shelves. Once the order is completed, they are loaded onto Goya owned trucks for delivery the next day. 

The Final Mile: Retail and E-Commerce

The final mile in the supply chain encompasses the last stage of delivery, where products make their way into the hands of consumers. This phase involves two distinct avenues: traditional retail and e-commerce.

1. Retail:

  • In traditional retail settings, products are showcased and made available for purchase in physical brick-and-mortar stores.
  • Retail logistics focus on optimizing various aspects of store operations to enhance the shopping experience for customers.

2. Store Layout Optimization:

  • Retail logistics involves strategically arranging products on shelves or racks to maximize visibility and accessibility for customers.
  • Efficient store layouts facilitate easy navigation and encourage impulse purchases, contributing to higher sales and customer satisfaction.

3. Inventory Management:

Making Sense of Logistics Terminology

Making sense of logistics terminology is crucial for understanding and effectively managing supply chain operations. Let’s delve deeper into some key terms and concepts:

1. Inventory Management: Inventory management involves the strategic oversight and control of goods as they move in and out of a company’s inventory. This includes activities such as inventory tracking, stock replenishment, and inventory optimization to ensure that the right quantity of goods is available at the right time and place. Effective inventory management helps minimize carrying costs, prevent stockouts, and maximize operational efficiency.

2. Just-in-Time (JIT): Just-in-Time (JIT) is an inventory management strategy that aims to minimize inventory levels by producing or purchasing goods only as they are needed for production or sale. This approach helps reduce excess inventory, storage costs, and waste while improving responsiveness to changes in customer demand. JIT requires close coordination between suppliers, manufacturers, and distributors to ensure timely delivery of goods as needed.

3. Warehouse Management System (WMS): A Warehouse Management System (WMS) is a software application used to manage and optimize warehouse operations. WMS automates and streamlines tasks such as receiving, storing, picking, packing, and shipping inventory within the warehouse. It provides real-time visibility into inventory levels, locations, and movements, allowing companies to efficiently manage warehouse space, improve inventory accuracy, and enhance order fulfillment processes.

4. Economic Order Quantity (EOQ): Economic Order Quantity (EOQ) is a mathematical formula used to determine the optimal order quantity that minimizes total inventory costs, including ordering costs and carrying costs. EOQ considers factors such as demand variability, ordering costs, and holding costs to find the balance between the costs of holding excess inventory and the costs of placing frequent orders. By calculating EOQ, companies can optimize inventory levels and minimize total inventory costs.

5. Safety Stock: Safety stock, also known as buffer stock, is extra inventory held to protect against fluctuations in demand or supply chain disruptions. It acts as a cushion to prevent stockouts and ensure that products are available to meet unexpected spikes in demand or delays in supply. Safety stock levels are determined based on factors such as demand variability, lead times, and service level targets to ensure adequate inventory availability while balancing inventory carrying costs.

6. Lead Time: Lead time is the amount of time it takes for an order to be fulfilled from the moment it is placed until the goods are received. Lead time includes various components, such as order processing time, production time, transportation time, and delivery time. Understanding lead times is essential for planning inventory levels, managing customer expectations, and optimizing supply chain performance.

7. Cycle Counting: Cycle counting is an inventory management technique that involves regularly counting a subset of inventory items within a warehouse or distribution center. Unlike traditional physical inventory audits, which require shutting down operations to count all inventory at once, cycle counting involves counting smaller batches of inventory on an ongoing basis. This allows companies to maintain accurate inventory records, identify discrepancies, and address inventory inaccuracies in real-time without disrupting operations.

8. Cross-Docking: Cross-docking is a logistics strategy that involves transferring goods directly from inbound transportation vehicles to outbound vehicles with minimal or no storage in between. This strategy reduces handling and storage costs, shortens order processing times, and improves inventory turnover by bypassing the traditional warehousing process. Cross-docking is commonly used for fast-moving, perishable, or time-sensitive goods to expedite delivery to customers.
