Scientific management aimed to improve economic efficiency, especially labor productivity, through analyzing and optimizing workflows. Pioneered by Frederick Taylor in the early 1900s, it involved developing scientific methods for each task to replace rule-of-thumb practices, scientifically selecting and training workers, and cooperating between workers and management. Frank and Lillian Gilbreth expanded on Taylor's work through motion and time studies to further reduce inefficiency and improve worker satisfaction. Scientific management transformed industries by standardizing best practices and rationalizing production processes.
