D) workers became another kind of interchangeable part

Under Frederick W. Taylor's theory of scientific management, workers were viewed as another kind of interchangeable part, with the focus being on efficient and standardized production processes rather than valuing individual worker skills or allowing workers to control the pace and scale of production. Workers were also encouraged to specialize in a narrow set of tasks rather than shifting frequently from one task to another.
