Answer: I believe you're looking for "Scientific Management" or "Taylorism."
Explanation: This approach was developed by Frederick W. Taylor in the early 20th century and is a fundamental concept in the field of management and industrial engineering. Taylorism involves breaking down tasks into their smallest components, analyzing each component for efficiency, and then standardizing and teaching the most efficient methods to workers to improve productivity and reduce waste. It is a systematic and data-driven approach to optimizing work processes.
