 The primary difference is that 5S includes two additional steps, Set in Order and Sustain, which are omitted in the simplified 3S (Sort, Sweep/Shine, Standardize) methodology. While 5S offers a comprehensive approach to workplace organization and efficiency, 3S provides a simplified, often daily, routine focusing on initial cleanup and process standardization, making it a quicker starting point for organizations. 

The 5S Methodology

5S is a Japanese methodology for creating and maintaining a clean, organized, and efficient workplace. 

Sort (Seiri): Identify and remove unnecessary items from the workplace.

Set in Order (Seiton): Arrange necessary items in a way that makes them easy to find and use.

Shine (Seiso): Clean the workplace and equipment to ensure they are in good working order and to prevent malfunctions.

Standardize (Seiketsu): Create standards and routines to maintain the first three S's.

Sustain (Shitsuke): Develop the discipline and commitment to continue the 5S practices over time and to foster a culture of continuous improvement. 

The 3S Methodology

Popularized by Paul Akers and the 2 Second Lean movement, 3S is a streamlined version of 5S that includes: 

Sort: Similar to 5S, this involves separating useful from unnecessary items.

Sweep/Shine: This step focuses on cleaning the workspace, often performed daily, to identify issues and keep the area clean.

Standardize: This focuses on creating standardized processes to address issues identified during sorting and cleaning, rather than just cleaning standards. 

Key Differences

Scope: 5S is a comprehensive system for workplace organization, while 3S is a simpler, entry-level approach.

Focus: 5S emphasizes creating a disciplined and sustained culture of improvement through all five steps. 3S focuses on an initial, often daily, routine of sorting, cleaning, and establishing basic standardized processes.

Application: 5S is a foundation for all improvement efforts, while 3S can be a quick way to start improving efficiency and cleanliness.
