5S and 6S are methodologies designed to improve workplace organization, efficiency, and safety.

5S stands for:

1. Sort (Seiri): Eliminate unnecessary items from the workspace.
2. Set in Order (Seiton): Organize the necessary items for easy access.
3. Shine (Seiso): Keep the workplace clean and tidy.
4. Standardize (Seiketsu): Establish standards for processes and organization.
5. Sustain (Shitsuke): Maintain and review standards regularly.

6S adds a sixth element, Safety. This emphasizes creating a safe working environment by identifying and mitigating hazards.

Together, these methodologies foster a culture of continuous improvement, enhance productivity, and promote safety in the workplace. Implementing 5S/6S can lead to significant reductions in waste and improved employee morale.
