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.
S
| Definition
|
Sort
| The act of removing any unnecessary items, including obsolete, defective, or excess items. Personal items should be removed from the work area, items that are no longer used should be discarded, and items (eg, tools) that are used infrequently should be stored away from the work area. |
Straighten
| The arrangement of items to allow for easy access, also known as "set-in-order." Items that are infrequently used should be easily accessible during daily operations. Containers that are used to store supplies should be clearly marked. |
Shine
| The cleanliness of the working area and equipment. Floors, work surfaces, equipment, and storage areas should be clean at all times. Garbage and recyclables should be collected and disposed. Safety information should be posted and any potential safety issues should be promptly solved. Fire extinguishers and emergency equipment should be clearly marked and functional. |
Standardize
| The identification of roles for keeping the area clean and orderly. 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. |
Sustain
| The continued empowerment of employees by management. 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. |
