The answer to your question is Scientific Management.

Scientific Management is a theory developed by Frederick Winslow Taylor in the early 20th century. Taylor's approach focused on analyzing and synthesizing workflows, with the aim of improving labor productivity. His methods involved studying the tasks that workers performed to determine the most efficient ways to carry them out. He would observe workers, measure their performance, and analyze their tasks to identify the best practices. After establishing these optimized methods, he would train workers to adopt them in order to enhance efficiency and productivity in the workplace.

This approach revolutionized industrial operations and laid the groundwork for modern management practices, emphasizing data-driven approaches to improve efficiency and reduce waste. Taylor's principles are still relevant in many organizational processes today, especially in manufacturing and operations management.
