Motion study examines the individual movements and actions a worker performs while completing a task, aiming to eliminate unnecessary motions and improve efficiency.

The question asks us to identify which type of study focuses specifically on the movements undertaken during a job. To understand this, we need to look at the scientific management techniques developed in the early twentieth century, particularly the pioneering work of Frank and Lillian Gilbreth.

When factories and businesses began applying scientific principles to work, they realized that efficiency could be improved not just by measuring how long a task took, but by analyzing how workers actually performed that task. What specific movements did they make? Were all those movements necessary? Could the sequence be improved?

Motion study is the systematic examination of the body movements, gestures, and physical actions a worker makes while performing a job. The Gilbreths broke down work into its smallest components—what they called "therbligs" (an anagram of Gilbreth)—such as reaching, grasping, positioning, and releasing. By filming workers and studying these micro-movements frame by frame, they could identify wasted effort: unnecessary bending, awkward reaches, redundant hand movements, or poor positioning of tools and materials.

The other options serve different purposes in work study:

  • Method study is broader—it examines the entire way a job is done, including the sequence of operations, workplace layout, and tools used, to find the best method overall.
  • Time study measures how long a task takes when performed at a standard pace, establishing time standards for planning and costing. …
