5S is an organizational method in Lean that provides a starting point for continuous improvement. It is a systematic way of creating a safe and efficient work environment for employees. Some organizations refer to this system as "6S" to emphasize safety, although safety should always be a consideration in each of the five steps.

| Definition
|
Sort
| The act of removing any unnecessary items or tools, including excessive, obsolete, or defective, items. A rule of thumb is that if an item is not used daily it should be removed from the immediate work area. Personal items should be removed from the work area, items no longer used should be discarded, and items used infrequently should be stored away from the work area. |
Straighten
| The arrangement of items to allow for easy access is also known as "set-in-order." Containers that are used to store supplies should be marked. Frequently used items should be stored close to the user. Items used together should be stored in the order in which they are used and together for easy access. Items that are infrequently used should be easily accessible during daily operations. |
Shine
| The cleanliness of the working area and equipment. Floors, work surfaces, equipment, and storage areas should be clean at all times. The cleaning process should be standardized and all staff trained and held accountable for a clean work area. Trash and recyclables should be collected and discarded or stored properly. Safety information should be posted and any potential safety issues should be promptly solved. Fire extinguishers and emergency equipment should be marked and functional. |
Standardize
| All management and staff members should know who needs to be responsible for each task and when it needs to be done. Organizations can achieve standardization through clear and detailed procedures and proper training. Periodic evaluation will help to guarantee that the standardization is in place. |
Sustain
| The continued empowerment of employees by management will help to sustain the designated work processes that reflect lean and 6 Sigma work processes.. All employees need to invest time and effort to sustain the principles of Lean. This is the last and most difficult step since it requires self-discipline and commitment by both management and staff. |
