The "5S" methodology is a workplace organization system that aims to improve efficiency and safety. It consists of five steps: Sort, Set in order, Shine, Standardize, and Sustain. Each step focuses on organizing and maintaining a clean and efficient workspace, which can lead to increased productivity and reduced waste. The first step, Sort, involves removing unnecessary items from the workspace. Next, Set in order means arranging tools and materials for easy access. Shine emphasizes cleanliness, while Standardize creates consistent practices. Finally, Sustain ensures that these practices are maintained over time, fostering a culture of continuous improvement.
