Before the COVID-19 pandemic rocked the world, factory workers were humming along, assembling products just after components were delivered. It was called “just-in-time” production. It was efficient, predictable and cost-effective.
Today, companies are scrambling to find parts, lock-in purchases — and hopefully prices — and work around estimated delivery schedules. It is a vastly different world.
For example, three years ago, people touring the Boeing 737 plant in Renton, Washington, saw 737s creeping down long assembly lines where wings, engines and tails were mounted on fuselages. Parts came from around the world and were added systematically, at the right time.
The fuselages were fabricated in Kansas, transported by rail to Washington. Other components arrived in containers by sea, rail and truck. Since each 737 was different, custom parts were added as the aircraft moved down the factory floor.
Success of “just-in-time” production hinged on timely deliveries. The benefit to companies was that they didn’t have to keep large inventories, which are cumbersome and costly.
