What is 6S?

6S is a workplace organization and management methodology that builds upon the well-known 5S system.

It is a comprehensive approach that helps create a clean, organized, and efficient work environment by focusing on six key principles: Sort, Set in Order, Shine, Standardize, Sustain, and Safety.

Origins of 5S and Evolution to 6S

The 5S system originated in Japan in the 1950s as a way to improve workplace efficiency and productivity. The five principles of 5S are; Seiri (Sort), Seiton (Set in Order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain). 

Over time, the 5S methodology has evolved, and many organizations have added a sixth “S” – Safety. This addition recognizes the critical importance of workplace safety and integrates it as a core component of the overall system.

The 6S approach provides a more holistic framework for creating a safe, organized, and efficient work environment.

Key Principles of 6S

The six key principles of the 6S methodology are:

  1. Sort (Seiri): Identifying and removing unnecessary items from the workplace, reducing clutter and potential hazards.
  2. Set in Order (Seiton): Organizing and labeling necessary items in a logical and accessible manner, ensuring efficient workflows.
  3. Shine (Seiso): Regular cleaning and maintenance of the workplace, keeping it in pristine condition.
  4. Standardize (Seiketsu): Establishing consistent work processes, responsibilities, and visual cues to maintain the 6S system.
  5. Sustain (Shitsuke): Maintaining it over the long term through ongoing training, audits, and continuous improvement.
  6. Safety (Anzen): Implementing safety measures, providing personal protective equipment (PPE), and promoting a culture of safety awareness.

By following these six principles, organizations can create a well-organized, clean, and safe work environment that fosters increased efficiency, productivity, and overall workplace satisfaction.

The 6S Steps Explained


The first step in this methodology is Sort. This involves identifying and removing any unnecessary items from the workplace.

This could include outdated documents, broken equipment, excess inventory, or any other items that are not essential for daily operations.

The goal is to create a clutter-free and organized work environment by getting rid of anything that is not needed. This improves workflow and productivity and reduces the risk of workplace hazards.

Set in Order

Once the unnecessary items have been removed, the next step is Set in Order. This involves organizing and labeling the remaining necessary items logically and efficiently.

This could include storing items in designated areas, using color-coding or labeling systems, and ensuring that everything has a designated and easily accessible place.

The goal is to create a streamlined and intuitive work environment where employees can quickly and easily find what they need.


The third step in this process is Shine. This involves regular cleaning and maintenance of the workplace.

This includes wiping down surfaces, sweeping and mopping floors, and ensuring that equipment is well-maintained and in good working order.

The goal is to create a clean, well-organized, and visually appealing work environment that promotes a sense of pride and ownership among employees.


Next is Standardize. This involves establishing consistent work processes and responsibilities throughout the organization.

This could include creating standardized operating procedures, checklists, and job descriptions, as well as ensuring that all employees are trained and held accountable for following these standards.

The goal is to create a consistent and efficient work environment where everyone knows their roles and responsibilities.


The fifth step is Sustain. This involves maintaining the 6S system long-term and ensuring that it becomes ingrained in the organization’s culture.

This could include regular audits, ongoing training and education, and rewarding employees for their adherence to the 6S principles.

The goal is to ensure that this system becomes a permanent part of the organization’s operations and is not just a temporary solution.


The final step in the 6S process is Safety. This involves implementing safety measures and personal protective equipment (PPE) to ensure the well-being of employees.

This could include installing safety guards on equipment, providing appropriate PPE such as hard hats, gloves, and safety glasses, and conducting regular job safety analysis (JSAs) to identify and mitigate potential hazards.

The goal is to create a safe and healthy work environment that protects employees from harm.

Benefits of Implementing 6S

Implementing the 6S methodology in the workplace can provide a wide range of benefits that can significantly improve overall operations and productivity. Let’s explore some of the key advantages of adopting the 6S system:
