Motion Study is the systematic analysis of the movements required to perform a task, aiming to identify and implement the most cost-efficient motions. This analytical process is a cornerstone of scientific management and focuses on improving efficiency, reducing waste, and enhancing productivity in various operations.
Historical Context and Contributions
Frederick W. Taylor
Frederick Winslow Taylor, often referred to as the “father of scientific management,” laid the foundation for motion study by advocating standardized work practices and efficiency. Taylor’s work in time study, which involves measuring the time taken to complete tasks, overlaps with motion study and has significantly influenced industrial management.
Frank and Lillian Gilbreth
Husband-and-wife team Frank and Lillian Gilbreth further developed the field. Frank Gilbreth introduced the use of motion pictures to study work activities, enabling more detailed and precise analysis. Lillian Gilbreth contributed to the human aspects of motion study, emphasizing the importance of considering workers’ well-being alongside efficiency.
Components of Motion Study
Basic Motions
Frank and Lillian Gilbreth identified basic motions called therbligs, which are the fundamental elements of a worker’s hand movements. These therbligs help in analyzing work tasks at an elemental level.
Time Measurement
Combining motion study with time study, analysts measure the time it takes to perform each motion. This helps in benchmarking and optimizing task performance.
Application in Industry
Motion study is widely applied in manufacturing, healthcare, and service industries to streamline operations. Common applications include:
- Assembly Line Optimization: Reducing wasted motions to increase productivity.
- Healthcare Processes: Streamlining patient handling and care procedures.
- Service Industries: Enhancing customer service interactions by simplifying and standardizing service tasks.
Examples
Assembly Line Work
In an assembly line context, a motion study might involve analyzing the steps taken by a worker to assemble a product, eliminating unnecessary movements, and rearranging tools and components for optimal reach and efficiency.
Surgical Procedures
In healthcare, motion studies are used to optimize surgical procedures, ensuring that all instruments are within easy reach and that each step follows logically from the previous one, thereby reducing surgery time and enhancing patient outcomes.
Comparisons and Related Terms
Motion Study vs. Time Study
- Motion Study: Focuses on the analysis and improvement of physical movements.
- Time Study: Measures the time taken to perform tasks and sets time standards.
Ergonomics
Ergonomics encompasses motion study but additionally focuses on designing tasks, tools, and environments to fit human capabilities and limitations.

Summary
Motion study, integral to scientific management, analyzes work to identify efficient motions for performing tasks. Developed mainly by Frederick W. Taylor and Frank and Lillian Gilbreth, it seeks to enhance workplace efficiency and productivity by minimizing wasteful movements. Applications span various industries, demonstrating its longstanding relevance and impact.
