In 1878, a machinist at a Pennsylvania steelworks noticed that his crew was producing much less than he thought they could. With stopwatches and time-motion studies, Frederick Winslow Taylor ran experiments to find the optimal way to make the most steel with lower labor costs. It was the birth of a management theory, called scientific management or Taylorism.

Critics said Taylor’s drive for industrial efficiency depleted workers physically and emotionally. Resentful laborers walked off the job. The U.S. Congress held hearings on it. Still, scientific management was the dominant management theory 100 years ago in October of 1922, when Harvard Business Review was founded.

It spread around the world, fueled the rise of big business, and helped decide World War II. And today it is baked into workplaces, from call centers to restaurant kitchens, gig worker algorithms, and offices. Although few modern workers would recognize Taylorism, and few employers would admit to it.
