The past 30 months have produced three distinct supply chain disruptions of meaningful scale: the semiconductor capacity rebalancing, the Red Sea shipping diversion, and the rare-earth materials availability constraints in 2025. Each disruption affected different industries and arose from different causes, providing a natural experiment in supply chain resilience that earlier crises did not.
What the data shows
Examining firms across the affected industries reveals that resilience outcomes correlate less with absolute supply chain investment than with several specific structural choices made before the disruption began.
Industry analysis suggests that firms that fared best across all three disruptions shared four characteristics: diversified supplier networks, real-time visibility into multi-tier supply structures, pre-negotiated alternative sourcing arrangements, and operational flexibility to absorb short-term cost increases without immediate price pass-through.
Firms that fared worst tended to share their own pattern: heavy reliance on single suppliers in geographically concentrated regions, limited visibility beyond first-tier suppliers, and procurement strategies optimised primarily for cost rather than for risk-adjusted resilience.
Lesson one — supplier diversification beyond first tier
Many firms believed they had diversified supplier networks because they used multiple first-tier suppliers. Closer examination during disruption revealed that those first-tier suppliers were drawing from common second- and third-tier sources, producing correlated rather than diversified risk. Firms that mapped multi-tier supplier dependencies before disruption were demonstrably better positioned to identify and address concentrated risk than firms that mapped only their direct suppliers.
Lesson two — visibility outpaces optimisation
Investment in supply chain visibility — real-time tracking of inventory, in-transit goods, and supplier production capacity — produced higher returns during disruption than investments in narrow optimisation. Firms with strong visibility could re-route quickly when conditions changed; firms with optimised but rigid supply chains often discovered problems too late to respond.
The implication is not that optimisation is irrelevant, but that visibility is the prerequisite for effective optimisation under volatile conditions. Firms investing in optimisation without first establishing visibility consistently underperformed during disruption.
Lesson three — pre-negotiated alternatives
Establishing alternative sourcing arrangements during a disruption is substantially more expensive and slower than establishing them in advance. Evidence suggests that firms with pre-negotiated alternative supplier agreements — even when those agreements were not actively used in normal conditions — were able to activate those alternatives in days rather than the weeks or months required by firms starting from scratch.
The cost of maintaining pre-negotiated alternatives is real but generally modest. Industry data indicates the cost premium ranges between 0.5 and 2 percent of total procurement spend, against potential disruption costs that have repeatedly run into double-digit percentages of revenue for affected firms.
Lesson four — operational and pricing flexibility
The firms that absorbed disruption costs without significant earnings impact tended to share two operational characteristics. First, they had operational flexibility to adjust production schedules, prioritise certain product lines, or substitute materials without significant retooling. Second, they had pricing flexibility to pass through cost increases over time without losing customers permanently.
Operational flexibility tends to be capital-intensive and is therefore concentrated in larger firms with greater investment capacity. Pricing flexibility, by contrast, is largely a function of competitive position and brand strength — areas where smaller firms can compete with larger peers.
What did not work
Three commonly-cited resilience strategies produced limited measurable benefit during the recent disruptions.
Reshoring and nearshoring — bringing supply chains closer to end markets — provided meaningful benefit only when paired with the four characteristics above. Geographic proximity alone, without diversification, visibility, alternatives, and flexibility, did not protect firms from supplier-specific disruption.
Larger inventory buffers helped during specific short-duration disruptions but proved costly and partially obsolete during longer disruptions, where the missing inputs were not the ones being buffered.
Vertical integration produced mixed results. In some cases it eliminated supplier risk but introduced operational complexity that exposed firms to other disruption modes.
Implications for procurement strategy
For procurement and operations leaders revisiting resilience strategy in the coming planning cycle, the evidence suggests prioritising the four-element framework — diversification, visibility, alternatives, flexibility — over individual interventions in isolation. Each element is partially substitutable for the others, but the combination consistently outperforms any single element pursued in isolation.
The more general principle is that supply chain resilience is structural rather than tactical. The firms that came through the past 30 months with limited disruption did not act faster during the crisis; they had built differently before it began.
