Which principle of scientific management involves providing detailed instructions to ensure adherence to developed methods?

The principle of scientific management that focuses on providing detailed instructions to ensure adherence to developed methods aligns closely with the concept of supervision and guidance. This principle emphasizes the importance of clear communication and structured processes in the workplace. By using detailed instructions, managers can ensure that employees perform tasks in ways that have been determined to be the most efficient and effective. This type of supervision helps standardize practices, reduces variability in performance, and enhances productivity.

To effectively implement scientific management, adherence to established methods is crucial, which is facilitated by the comprehensive direction and oversight provided by supervisors. This practice not only guides employees in performing their roles but also fosters a systematic approach to work that is central to scientific management's objectives of optimizing efficiency and productivity.
