5-S is a housekeeping methodology that involves 5 steps: sorting, self-arranging, spic and span, standardizing, and self-disciplining. The methodology aims to improve efficiency and productivity, maintain safety and cleanliness, and ensure good product quality and process control. The 5 steps are: sorting to separate needed and unneeded items; self-arranging items for easy access and use; cleaning and maintaining a spic-and-span workplace; standardizing processes and storage locations; and self-disciplining to follow standards and maintain the 5-S system. Proper implementation of 5-S provides benefits like reducing errors, lowering costs, improving workplace organization and visual controls, and increasing motivation.
