5S is a workplace organization method that involves 5 principles: sorting, straightening, shining, standardizing, and sustaining. It aims to establish efficiency and order through eliminating waste and maintaining a clean work environment. The 5S principles involve sorting through all items in a workspace to identify unnecessary items, setting items in designated areas by frequency of use, cleaning and shining the workspace, standardizing processes and responsibilities, and sustaining the organized system through ongoing audits and improvements. Implementing 5S creates benefits like reduced search time, improved space utilization, and a safer, more productive work area.
