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, pioneered by Frank and Lillian Gilbreth as part of scientific management, is a method focused on observing, dissecting, and optimizing the physical actions performed during a task. Its primary objectives are:

• To detect and eliminate inefficient or superfluous movements.
• To boost worker efficiency by minimizing fatigue and wasted time.
• To elevate productivity through the refinement of task-related physical motions.

Analysis of Choices:

• (A) aligns with motion study; the examination of physical movements is central to this technique.
• (B) pertains primarily to time study, though it can have indirect relevance during motion analysis.
• (C) is not an aim of motion study. "Eliminating unnecessary diversities in production" is a broader concern of production planning and standardization, not a specific objective of motion analysis.
• (D) directly reflects a goal of motion study: pinpointing and removing inefficient movements.
