Question

Explain the following techniques of Scientific Management : (i) Fatigue study, (ii) Motion study.

• A. Subjective/Descriptive Question
• B. Not Applicable
• C. Not Applicable
• D. Not Applicable

Hint:

Remember the distinct focus of each study: - Fatigue Study focus: Rest intervals (frequency, duration) to restore human stamina. - Motion Study focus: Physical body movements (eliminating unproductive steps) to streamline workflow.

Answer 1

The Correct Option is A

Concept: F.W. Taylor developed several techniques of Scientific Management to introduce scientific objectivity into shop-floor operations, moving away from rule-of-thumb methods. Both fatigue study and motion study are key components of Taylor's Work Study approach, designed to maximize worker efficiency and minimize waste. Step 1: Detailed Analysis of Fatigue Study
A person bound to work continuously for long hours will inevitably experience physical and mental strain, leading to a drop in efficiency. Fatigue study scientifically determines the parameters of rest required to maintain productivity.

• Objective: To determine the frequency of rest intervals, the duration of each rest break, and the total number of rest intervals needed during a working day.

• Scientific Methodology: Rather than relying on a manager's personal judgment, Taylor suggested observing workers scientifically. An average worker is tracked to see how many hours of continuous work cause their productivity to decline. The rest interval provided should be long enough to allow the worker to regain their physical stamina and return to work at full capacity.

• Impact: This approach helps prevent industrial accidents, reduces health issues among workers, and maintains a stable, optimal level of production.

Step 2: Detailed Analysis of Motion Study
Motion study involves the close observation and analysis of the physical movements performed by a worker while executing a given task.

• Objective: To identify and eliminate unproductive, wasteful, and redundant movements, ensuring that tasks are completed in the minimum possible time with minimal effort.

• Scientific Methodology: Managers use tools like stopwatches, movie cameras, and symbols to record and track different human movements (such as lifting, bending, sitting, reaching, and moving materials). These movements are then classified into three distinct categories:

• Impact: By eliminating unproductive movements and redesigning the workspace so tools and materials are within easy reach, organizations can significantly cut down task completion times and boost overall worker efficiency.
