Some supply chains look strongest just before their weaknesses become visible.
That is how Dr. Uppiliappan Gopalan opens the second chapter of Navigating Supply Chain Challenges, describing a familiar scene: a review meeting where every number earns approval. Inventory has fallen, supplier numbers have reduced, factories are operating close to capacity, and freight expenditure remains under control.
The confidence in that room, he writes, is usually deserved. Yet a different question sits quietly behind those achievements.
How Much Room Remains When One Assumption Changes?
A supplier that has delivered reliably for years may suddenly lose capacity. A port may become congested. A border process may slow. None of these events needs to be extraordinary for pressure to begin travelling through the business. At first, the organisation often feels protected, because some inventory remains available and alternative suppliers appear in the approved database.
A few days later, the view changes. Inventory begins falling faster than expected. The second supplier needs fresh tooling. Another route adds three weeks. Production planners start deciding which orders should receive the remaining material.
“The disruption has barely changed. The organisation’s choices have.”
Why Efficiency Made Sense in the First Place
Dr. Gopalan is careful not to frame efficiency as a mistake. Material sitting inside a warehouse occupies space, requires handling, and keeps cash tied up before the customer has paid for the finished product. Fewer suppliers can strengthen quality monitoring and purchasing leverage. A facility operating near full capacity spreads fixed expenditure across more units and produces stronger returns.
Nothing about these decisions is careless, he writes. They represent disciplined management under conditions that have remained broadly stable. Each decision is supported by the success of the decision before it, until, gradually, the organisation begins removing more than cost.
The Difference That Matters Most
Efficiency concerns how carefully an organisation uses cost, time, inventory and capacity. Resilience concerns what happens after the expected pattern changes, whether the organisation can recognise pressure early, continue operating while alternatives are assessed, and bring another supplier, route or material online before customers ever feel the effect.
Efficiency strengthens performance while operating assumptions remain valid, Dr. Gopalan writes. Resilience determines how the network behaves when those assumptions change.
