The supply chain disruptions of 2020-2022 exposed a strategic assumption that most global businesses had been making for thirty years: that efficiency and resilience are compatible optimization targets. They are not.
The Just-in-Time Vulnerability
Just-in-time manufacturing and inventory management, pioneered by Toyota and adopted across global industry, optimizes for efficiency: minimize inventory, maximize asset utilization, and reduce working capital requirements. Under normal operating conditions, it is extraordinarily effective. Under disrupted conditions — pandemics, geopolitical events, natural disasters — it is extraordinarily fragile, because it eliminates exactly the buffers that absorb shocks.
The semiconductor shortage that began in 2020 and persisted through 2022 was not primarily a production problem — semiconductor fabs were operating at capacity. It was an inventory problem: companies that had optimized out their safety stock had no buffer to absorb a demand surge or supply disruption.
The Strategic Recalibration
The strategic response has been a systematic recalibration of the efficiency-resilience trade-off across global industry. Companies are increasing safety stock levels, diversifying supplier bases away from single-country concentration, investing in regional manufacturing capacity closer to end markets, and building more sophisticated supply chain monitoring and scenario planning capabilities.
This recalibration has a cost — inventory carrying costs, manufacturing inefficiency, and supplier complexity all increase. But the post-COVID consensus among strategic planners is that the cost of resilience is lower than the cost of fragility, properly accounting for the tail-risk scenarios that just-in-time systems cannot survive.
The Geopolitical Dimension
The supply chain recalibration has been accelerated by a geopolitical shift toward strategic decoupling between the United States and China. The CHIPS Act, the Inflation Reduction Act’s domestic manufacturing incentives, and the broader policy push toward supply chain repatriation represent a structural change in the incentive environment for global manufacturing location decisions that will play out over the next decade and reshape the geography of global production.
