Analogy

Imagine a dance routine where every movement is carefully choreographed to be efficient and visually appealing. The principles of motion economy in work design are like the choreography of this dance routine. Just as each movement in the dance is analyzed and optimized to create a seamless performance, the principles of motion economy analyze and optimize individual motions in a task to improve overall work efficiency.
