When the Chain Breaks:
Understanding Supply Chain Disruption and How to Build Resilience
From the Covid-19 pandemic to Houthi attacks on Red Sea shipping lanes, and Hourmuz Straits disruptions are no longer rare exceptions. They are the new normal. Here’s what resilience really means — and how businesses can build it.

What is a supply chain?
A supply chain is a network of organisations, people, activities, information, and resources involved in moving a product or service from supplier to customer. It sounds simple. But consider a single commercial aircraft: its wings are built in Nagoya, its rudder in Chengdu, its landing gear in Gloucester, and its engines in Ohio. Every node in that network is a potential point of failure.
The same complexity applies to electronics, automobiles, pharmaceuticals, and even the food on supermarket shelves. Modern supply chains are marvels of global coordination — and deeply vulnerable to disruption.
What counts as a disruption?
A supply chain disruption is any event that slows or stops the flow of goods and services. Disruptions differ in three critical dimensions: their severity, their frequency, and our ability to anticipate them. A factory fire affects one node — low severity, high local impact. A pandemic or geopolitical conflict can paralyse entire global systems simultaneously.
- Natural disasters — earthquakes, hurricanes, floods affecting production or transport routes
- Geopolitical conflict — wars, sanctions, and border closures disrupting trade
- Health pandemics — simultaneous disruption to supply, demand, production and distribution
- Cyberattacks — malicious attacks on logistics and procurement systems
- Labour disputes — strikes, lockouts, and workforce shortages halting operations
- Demand spikes — sudden surges creating shortages throughout upstream supply
Disruption categories adapted from Pettit, Fiksel & Croxton (2010) and GEP Supply Chain Research.
| CASE STUDY — COVID-19 The disruption that broke all records The Covid-19 pandemic was unprecedented in human history. It caused simultaneous interruptions across supply, demand, production, and distribution — all at once, globally. With lockdowns, travel bans, and border closures, supply chains could only function for essentials and medical goods. No risk model had anticipated an event of this magnitude, frequency, and duration. |
The Red Sea crisis: a live case study
Since October 2023, Houthi attacks on commercial vessels in the Red Sea and the Bab al-Mandeb Strait have forced a major rerouting of global shipping. The numbers tell the story clearly.
| 35,000 vessels pass through the Red Sea annually, ~10% of global GDP | −66% fall in Suez Canal transits since diversions around Africa began | +8.5 days extra transit time via Cape of Good Hope vs the Red Sea route |
Ships rerouted around the Cape of Good Hope travel roughly 13,500 nautical miles instead of 10,000 — adding over a week to journey times and raising fuel costs by an estimated 10–20%. War-risk insurance premiums in the Eastern Mediterranean surged by 50–100%. These costs pass through the supply chain and eventually land with consumers.
Some companies responded by switching to intermodal transport — shipping goods by sea to Dubai, then transferring to air freight for onward delivery. It is faster, but at significantly higher cost. The lesson: route diversification is itself a resilience capability, but it must be built before the crisis strikes.
So what is resilience?
In engineering, resilience means the ability of a material to recover its size and shape after deformation — think of a coil spring. In supply chain terms, multiple researchers have defined it differently, but a common thread runs through all of them.
| ACADEMIC CONSENSUS What resilience means across disciplines From ecology: the ability to rebound from disturbance while maintaining integrity. From psychology: the ability to bounce back from adversity. From supply chain research (Rice & Caniato, 2003): the ability to react to an unexpected disruption and restore normal operations. From Fiksel (2006): the capacity of complex industrial systems to survive, adapt, and grow in the face of turbulent change. |
“Resilience is not just about bouncing back. It’s about surviving, adapting, and growing through disruption.”
Where vulnerability hides: the key risk factors
Research by Pettit, Fiksel & Croxton (2010) identified six major vulnerability factors that make supply chains susceptible to disruption. Understanding where your chain is exposed is the first step to addressing it.
| Factor | What it means in practice |
| Turbulence | Rapid, unpredictable changes in external factors — geopolitics, currency, demand, technology failures, pandemics |
| Deliberate threats | Intentional attacks — terrorism, sabotage, cyberattacks, labour disputes |
| External pressures | Political/regulatory change, social and environmental pressures that indirectly constrain the business |
| Resource limits | Constraints on supplier capacity, raw materials, utilities, or human resources |
| Connectivity | High interdependence and reliance on outside entities — scale of outsourcing, single-source suppliers |
| Supplier/customer disruptions | Susceptibility of partners to external forces — supplier reliability, customer instability |

Critically, researchers have called for health pandemics and regional geopolitical conflicts to be formally recognised as strategic vulnerability factors — categories that earlier frameworks did not account for at sufficient severity.
Five practical steps to build resilience
- 1. Create an emergency plan. Set aside contingency funds and define response protocols before you need them. A plan drafted under crisis pressure is rarely a good plan.
- 2. Build strategic inventory buffers. Maintain a few months of stock for critical components — not everywhere, but at the nodes where failure would be most painful. This also buys time to activate alternative suppliers.
- 3. Conduct a supply chain audit. Identify your weakest links. Map tier-2 and tier-3 suppliers. Assess social, environmental, and political exposure across your network.
- 4. Qualify backup suppliers across geographies. Diversification is fundamental. Suppliers in different regions mean no single political or natural event can cut you off entirely.
- 5. Invest in technology and visibility. AI and ML-driven platforms can identify threats before they escalate. Consider appointing a dedicated chief risk officer to own this agenda.
Three strategies for restructuring your supply chain
BCG research identifies three degrees of supply chain transformation, each suited to different risk profiles and industries.
| Revised global chain Small strategic changes: add redundant capacity, qualify more suppliers, improve visibility — while keeping existing cost advantages. | Migrated chain Shift a portion of production to reduce geopolitical exposure, e.g. moving manufacturing from China to Vietnam or India. | Regionalised chain Move production closer to end markets. Each regional cluster serves its own demand, reducing global interdependency. |

The bottom line: resilience is a strategic imperative
Global supply chain networks are dynamic and continuously exposed to geopolitical disruptions and challenges. The companies that survive and sustain themselves through turbulence are those that have invested in resilience — through redesign, restructuring, and the ability to rebound quickly.
The WEF Global Risks Report 2024 ranked disrupted supply chains for critical goods and food among the top ten most likely material crises globally. This is no longer a niche operational concern. It sits at the boardroom table.
Building resilient supply chains requires more than contingency plans. It demands digitalisation, strategic alliances, and the organisational flexibility to capture new sources of competitive advantage — even in the middle of a crisis. The disruptions of the coming years are already forming. The question is whether your supply chain will bend, or break.
