Which principle of Scientific Management emphasizes the efficiency of workers?

The principle that emphasizes the efficiency of workers is work specialization. This concept entails breaking down complex tasks into simpler, more manageable components, allowing workers to focus on a specific aspect of the overall task. By doing this, workers can develop greater proficiency and speed in their designated roles, leading to increased productivity.

Work specialization enhances efficiency because it reduces the time spent switching between different tasks, minimizes the learning curve associated with varied activities, and helps workers become exceptionally skilled in their specific jobs. This idea aligns with the core principles of Scientific Management, which seeks to optimize task performance and improve overall organizational efficiency through systematic analysis and structured work processes.

Other principles mentioned, such as unity of command and equity among workers, focus on organizational structure and fairness rather than directly on worker efficiency. Similarly, standardization of tasks relates more to uniformity in processes rather than individual worker efficiency, making work specialization the most relevant choice in the context of enhancing worker productivity.
