5S is a philosophy and methodology for organizing and managing workspaces using a five-step process: Sort, Set in Order, Shine, Standardize, and Sustain. The 5S approach aims to improve efficiency and reduce waste by eliminating unnecessary items, properly storing and labeling necessary items, cleaning and maintaining an organized workspace on a regular basis, standardizing processes, and sustaining these practices over time. Implementing 5S can lead to benefits like improved teamwork, identification and reduction of waste, improved productivity and safety, and a more positive work environment. The five steps are applied through specific activities and build upon each other to help establish strong workplace management practices.
