In the story of how the modern world was constructed, Toyota stands out as the mastermind of a monumental advance in industrial efficiency. The Japanese automaker pioneered so-called Just In Time manufacturing, in which parts are delivered to factories right as they are required, minimizing the need to stockpile them.
Over the last half-century, this approach has captivated global business in industries far beyond autos. From fashion to food processing to pharmaceuticals, companies have embraced Just In Time to stay nimble, allowing them to adapt to changing market demands, while cutting costs.
But the tumultuous events of the past year have challenged the merits of paring inventories, while reinvigorating concerns that some industries have gone too far, leaving them vulnerable to disruption. As the pandemic has hampered factory operations and sown chaos in global shipping, many economies around the world have been bedeviled by shortages of a vast range of goods — from electronics to lumber to clothing.
In a time of extraordinary upheaval in the global economy, Just In Time is running late.
“It’s sort of like supply chain run amok,” said Willy C. Shih, an international trade expert at Harvard Business School. “In a race to get to the lowest cost, I have concentrated my risk. We are at the logical conclusion of all that.”

But the breadth and persistence of the shortages reveal the extent to which the Just In Time idea has come to dominate commercial life. This helps explain why Nike and other apparel brands struggle to stock retail outlets with their wares. It’s one of the reasons construction companies are having trouble purchasing paints and sealants. It was a principal contributor to the tragic shortages of personal protective equipment early in the pandemic, which left frontline medical workers without adequate gear.
