Supply Chain

Shipping & Freight Definitions — cargo, logistics and transport terms from Apparel Search

A supply chain is a network of facilities and distribution options that performs three functions: procurement of materials, transformation of those materials into intermediate and finished products, and distribution of the finished products to customers. In its simplest layout the chain is a one-way sequence of processes, each supplying the next. In real-world situations the processes form a supply network, where processes can supply each other in flexible patterns. In manufacturing, a supply chain has three main parts. The supply side concentrates on how, where from and when raw materials are procured and supplied to manufacturing. Manufacturing converts the raw materials into finished products. Distribution ensures the finished products reach final customers through a network of distributors, warehouses and retailers. The chain can be said to start with the suppliers of your suppliers and end with the customers of your customer. For clothing, that means fiber and fabric suppliers, garment factories, shipping and warehousing, and finally the stores and shoppers who buy the finished apparel.

A supply chain is a chain of processes which supply one to another. In its most simple layout, the chain is a one-way sequence of processes:

process P(1) ===> P(2) ===> P(3) ===> ... ===> P(n)

In more complex, real-world situations, the involved processes can form a whole supply network where processes can supply to each other and form flexible patterns. This concept can be applied to many types of processes, e.g. in the field of manufacturing, but also in IT for example or in finance.

-- Manufacturing

A supply chain essentially has three main parts, the supply, manufacturing and distribution:

  • The supply side concentrates on how, where from and when raw materials are procured and supplied to manufacturing.
  • Manufacturing converts these raw materials to finished products and
  • Distribution ensures that these finished products reach the final customers through a network of distributors, warehouses and retailers (Retailer Definition).

The chain can be said to start with the suppliers of your suppliers and ends with the customers of your customer.

-- Other fields

As indicated above, the idea of modeling processes as chains can be applied to other fields as well: the concept is useful to show dependencies between all involved objects. In an IT system, programs or modules use input data and deliver output for other modules.

The Apparel Supply Chain Step by Step

In clothing, the chain begins long before a garment is sewn. Fiber is grown or manufactured, spun into yarn, woven or knitted into fabric, dyed and finished, then cut and sewn into garments in a factory. Trims such as buttons, zippers, labels and packaging are procured from their own suppliers and must arrive at the factory on time, or a finished order cannot ship. Completed garments are inspected, packed, and moved by truck, rail, ship or air to an importer's warehouse or distribution center. From there, distribution splits the bulk shipment into smaller allocations for individual stores or for direct shipment to online customers. Returns travel back up the chain for inspection, resale, repair or recycling. A delay at any step, a late fabric delivery, a missed vessel, a congested port, pushes every later step back, which is why fashion calendars build in lead time at each stage.

Why the Supply Chain Matters

Every handoff in the chain adds cost and time, and every facility in the network holds inventory that has already been paid for. Efficient chains reduce that cost by forecasting demand, ordering materials in the right quantities, and keeping goods moving rather than sitting in warehouses. Poor visibility is the classic problem: if a retailer cannot see where fabric, production and shipments actually stand, it reacts late to delays and either runs out of popular styles or ends the season with excess stock to mark down. Modern supply chain practice therefore stresses shared information between suppliers, manufacturers, carriers and retailers, tracked shipments, and backup options for critical materials. Sustainability and labor standards are also managed through the chain, because a brand is responsible in the eyes of its customers for conditions and environmental impact at facilities it does not own, from fiber production through factory sewing to final delivery.

Inventory, Warehouses and Retail Distribution

Distribution is where the supply chain meets the customer, and it is more than trucking finished goods to a store. Distribution centers receive bulk shipments, check them against orders, store them briefly, and then pick, pack and dispatch the exact mix of styles, colors and sizes each store or online order needs. Cross-docking can move some goods straight from an inbound vehicle to an outbound one with minimal storage, speeding fresh seasonal stock to the selling floor. Inventory positioning is a constant trade-off: holding stock close to customers shortens delivery time but spreads inventory across many locations, while centralizing it in fewer warehouses lowers total stock but adds transit time. Retailers also plan for the reverse flow, because returned clothing must be collected, inspected and routed back to sale, to an outlet, to repair or to recycling. A supply chain that handles both directions cleanly protects margin twice, once by getting product to the customer efficiently and once by recovering value from what comes back instead of writing it off.

Information is what holds these physical flows together. Purchase orders, production updates, advance shipping notices, tracking events and sales data all travel along the chain beside the goods themselves. When that information is accurate and shared early, factories schedule work sensibly, carriers reserve the right capacity, warehouses staff for arrivals they can foresee, and stores know what is coming and when. When it is late or wrong, every partner adds extra time and extra stock as insurance, and the customer pays for that insurance in the final price.

Common Questions

What are the three main parts of a supply chain?

The three parts are supply, manufacturing and distribution. Supply procures raw materials, manufacturing converts them into finished products, and distribution delivers those products to customers through distributors, warehouses and retailers.

Where does a supply chain start and end?

A supply chain starts with the suppliers of your suppliers and ends with the customers of your customer, covering every facility and process between raw material and final buyer.

Is a supply chain always a straight line?

No. The simplest layout is a one-way sequence of processes, but real supply chains form a network where processes can supply each other in flexible patterns.
