Micromotion analysis involves__________________?
Show answer Hide answer
Answer: D. subdivision of an operation into therbligs and their analysis
Explanation
Micromotion analysis subdivides complex manual operations into fundamental elemental motions. These elemental motions are formally known as therbligs for detailed industrial study. Breaking down tasks allows engineers to eliminate inefficient and unnecessary worker movements. Frank and Lillian Gilbreth pioneered motion study by defining basic elemental motions. The term therblig is an anagram of the surname Gilbreth used in engineering. High-speed film cameras capture detailed operator movements for frame-by-frame workplace analysis.
Assembly line manufacturers use micromotion studies to optimize repetitive manual workstation layouts. Ergonomic workstation designs rely on therblig analysis to reduce worker fatigue injuries. Improving assembly efficiency through motion breakdown significantly increases daily manufacturing output. An enlarged view contradicts the fundamental microscopic nature of detailed motion study. Analyzing only one stage is too narrow and ignores the comprehensive therblig breakdown. Motion study of small components focuses on parts rather than human body therbligs.
