5S is the name of a workplace organization method that uses a list of
five Japanese words: seiri, seiton, seiso, seiketsu, and shitsuke.Transliterated into Roman Script,
they all start with the letter "S".[1] The list describes how to organize a work space for efficiency and
effectiveness by identifying and storing the items used, maintaining the area and items, and
sustaining the new order.[2] The decision-making process usually comes from a dialogue about
standardization, which builds understanding among employees of how they should do the work.
In some quarters, 5S has become 6S, the sixth element being safety.[3]
Other than a specific stand-alone methodology, 5S is frequently viewed as an element of a broader
construct known as visual control,[4]visual workplace,[5] or visual factory.[6][7] Under those (and similar)
terminologies, Western companies were applying underlying concepts of 5S before publication, in
English, of the formal 5S methodology. For example, a workplace-organization photo from Tennant
Company (a Minneapolis-based manufacturer) quite similar to the one accompanying this article
appeared in a manufacturing-management book in 1986.[8]
