Question

The objective of motion study is not to ___

• A. Study the movement undertaken while completing a task.
• B. Determine the time taken to complete a task.
• C. Eliminate the unnecessary diversities in production.
• D. Eliminate the unproductive movements undertaken while completing a task.

Hint:

Motion study focuses on minimizing unnecessary physical movements to increase worker efficiency—not on managing production diversities.

Answer 1

The Correct Option is C

Motion Study is a technique of scientific management developed by Frank and Lillian Gilbreth. It involves observing, analyzing, and improving the physical movements involved in performing a task. The core purpose is to:

• Identify and remove unproductive or unnecessary motions.
• Improve the efficiency of workers by reducing fatigue and time wastage.
• Enhance productivity by streamlining work-related physical movements.

Explanation of Options:

• (A) is correct for motion study — studying physical movements is fundamental.
• (B) relates to time study, but may still be tangentially connected during motion analysis.
• (C) is not an objective of motion study — "eliminating unnecessary diversities in production" is a broader production planning or standardization issue, not specific to motion analysis.
• (D) is a direct goal of motion study — identifying and eliminating wasteful movements.
