5S Method
5S is a systematic method for workplace organization and cleanliness. The five steps: Sort, Set in Order, Shine, Standardize, Sustain.
The 5S method originates from the Toyota Production System and creates the foundation for every further improvement process. A messy workplace hides problems -- 5S makes them visible.
The five steps: Seiri (Sort -- remove the unnecessary), Seiton (Set in Order -- a fixed place for everything), Seiso (Shine -- clean and inspect the workplace), Seiketsu (Standardize -- establish rules), Shitsuke (Sustain -- maintain standards).
5S is not a one-time cleanup but an ongoing process. The fifth step (Sustain) is the hardest: It requires regular audits and a culture where orderliness is understood as value creation.
Measurable effects of 5S: Less search time (typically 10-30 minutes per shift), fewer accidents, faster changeovers, higher quality through visual controls, and better employee morale from a pleasant workplace.
Practical Example
In a tool crib, 340 tools are inventoried. After Step 1 (Sort), 210 remain -- the rest are defective, duplicated, or obsolete. After Step 2, each tool gets a marked spot with a shadow board. Search time per tool drops from 3.5 minutes to 15 seconds.
How Leanshift Helps
Leanshift documents the current state before and after 5S measures. With the stopwatch, you capture search times and travel times to make the effect of improvements measurable.
Frequently Asked Questions
Is 5S just cleaning up?
No. 5S is a systematic process that makes problems visible. Clean, organized workplaces are the prerequisite for standardization, error prevention, and continuous improvement.
How long does a 5S implementation take?
A 5S workshop for one area typically takes 2-5 days. The first three S's are quickly achievable. Standardize and Sustain (S4 and S5) require several months of consistent follow-through.
Is there also a 6S?
Sometimes Safety is added as a sixth S. In practice, however, workplace safety is integrated into all five steps, particularly in Sort and Shine.
