For decades, supply chain performance was measured by one overriding objective: efficiency. Businesses invested heavily in reducing inventory, shortening lead times, consolidating warehouse networks and removing unnecessary costs from their operations. Leaner supply chains were widely seen as stronger supply chains.
Today, that assumption is being challenged.
Disruptions are no longer isolated events that happen once every few years. Port congestion, supplier shortages, transport delays, infrastructure constraints and shifting customer demand have become familiar parts of the logistics landscape. The question is no longer whether disruption will occur, but how well a business can respond when it does.
An efficient supply chain is designed for normal operating conditions. A resilient supply chain is designed for the exceptions.
When Efficiency Creates Risk
Lean operations have transformed supply chains around the world. Lower inventory levels reduce carrying costs, fewer suppliers simplify procurement and centralised distribution networks often improve operational efficiency.
Those same decisions, however, can also reduce flexibility. A manufacturer relying on a single supplier may benefit from lower purchasing costs, but a disruption at that supplier can quickly affect production. Likewise, a centralised distribution centre may reduce operating expenses, yet any disruption at that facility can impact customers across an entire region.
Efficiency remains essential, but many businesses are recognising that removing every buffer from the supply chain can introduce new risks that are far more expensive when something goes wrong.
The Return of Strategic Buffers
For years, holding additional inventory was often viewed as inefficient. Today, that conversation is becoming more balanced.
Safety stock, once seen primarily as an added cost, is increasingly being recognised as a practical way to manage uncertainty. The same applies to supplier diversification. While working with multiple suppliers can increase procurement complexity, it also reduces dependence on a single source for critical materials or components.
These decisions don’t represent a move away from efficiency. They reflect a growing recognition that resilience sometimes requires carefully planned redundancy rather than eliminating every spare capacity within the network.
Looking Beyond a Single Distribution Centre
For many businesses, operating from one large distribution centre has always made financial sense. It can simplify operations, reduce overheads and make inventory easier to manage. The challenge comes when that one facility experiences delays or has to support customers spread across a large geographic area.
That’s why some organisations are taking another look at how their networks are set up. Regional distribution centres may cost more to operate, but they can shorten delivery times, reduce transport distances and make it easier to keep goods moving when one part of the network comes under pressure.
Technology is helping businesses make those decisions with greater confidence. Instead of relying on assumptions, supply chain teams can see how inventory is moving, where transport delays are occurring and which parts of the network are carrying the most risk.
Looking Beyond the Lowest Cost
For a long time, supply chain performance was judged largely on cost. Lower transport spend, leaner inventory and better warehouse utilisation were all signs of an efficient operation.
Those measures still matter, but they’re no longer telling the whole story. Businesses are also asking different questions. How quickly can we recover if a supplier can’t deliver? How much disruption can our network absorb before customers feel the impact? Are we meeting service expectations consistently, even when conditions change?
Those questions don’t replace efficiency – they add another layer to it. The strongest supply chains aren’t always the cheapest to run. More often, they’re the ones that continue performing when the unexpected becomes part of the working day.
