2 Supply Chain Strategy and Network Design

Link strategy to network design

A supply chain strategy translates business priorities into choices about how suppliers, facilities, inventory, information, and transportation will be used to serve target customers. Network design should follow that strategy: a company competing on low prices may prioritize efficient operations, while one competing on rapid delivery or customization may need more flexible capacity and shorter lead times.

There is no single best network for every product or market. Choices should reflect customer expectations, demand patterns, product characteristics, supplier capabilities, costs, risks, and sustainability goals. Design elements must also fit together. For example, a next-day delivery promise requires suitable inventory locations, warehouse capacity, and transportation service.

Choose a network configuration

Network design establishes the supply chain’s structure and major flows. Planners decide which suppliers, manufacturing sites, and distribution facilities to use; where to locate facilities and how much capacity each should have; which customers or regions each facility will serve; where to hold inventory; how products will move between nodes; and which transportation modes and routes to use.

A centralized network can pool inventory and reduce the number of facilities, but it may increase delivery distances or make the company more dependent on a few locations. A more distributed network can place products closer to customers and shorten delivery times, but generally requires additional facilities, inventory, and coordination.

Network models help compare alternatives by estimating total cost and service under different assumptions about demand, capacity, and transportation. Since assumptions can change, planners should test more than one plausible scenario rather than treat a single forecast as certain.

Balance responsiveness and cost

Responsiveness is the speed with which a supply chain completes customer order-to-delivery activities. Shorter lead times, strategically located inventory, flexible capacity, and fast transportation can improve it. These choices can increase operating costs, so companies should target speed where customers value it most. ASCM’s SCOR framework treats order fulfillment cycle time as a key responsiveness measure.

Design for resilience

Resilience is the ability to withstand, recover from, and adapt to disruptions. Network design can support resilience through qualified alternative suppliers, backup capacity, flexible routing, visibility into supply risks, and contingency plans.

These options have costs. The goal is not to duplicate every resource, but to protect important products and flows against risks whose consequences justify the investment. OECD analysis emphasizes evaluating resilience alongside efficiency and sustainability rather than optimizing one objective in isolation.

Include sustainability in design

Sustainability should be considered throughout the network, not only in transportation. Facility locations, energy use, packaging, inventory obsolescence, waste, labor practices, and product returns can all affect environmental and social outcomes.

Companies can track measures such as greenhouse-gas emissions, energy and materials used, waste, and selected social indicators. For freight, the U.S. Environmental Protection Agency’s SmartWay program helps companies measure and benchmark transportation efficiency and emissions.

Design choices can involve trade-offs. Consolidating shipments can improve vehicle utilization, while faster delivery or a more dispersed network may increase transport activity. The best decision depends on the service promise, actual operating data, and the company’s wider objectives.

Compare distribution network options

Consider an online retailer choosing between one national warehouse and several regional facilities. A single warehouse may simplify inventory management and reduce facility costs, but longer delivery distances could slow service. Regional facilities may improve delivery speed and offer alternatives if one site is disrupted, but they require additional capacity and careful inventory allocation.

The retailer should compare the designs using total cost, delivery time, service reliability, disruption scenarios, and environmental measures. A hybrid design might hold regional stock for fast-moving products and centralized stock for slower-moving items.

Bring the design choices together

Supply chain network design translates business strategy into decisions about facilities, capacity, suppliers, inventory, and flows. Centralization, decentralization, responsiveness, resilience, cost, and sustainability have interconnected effects. A sound design makes these trade-offs explicit, tests alternative scenarios, and measures performance against customer needs and business priorities.
