5S is a method for organizing a workplace, especially a shared workplace (like a shop floor or an office space), and keeping it organized. It's sometimes referred to as a housekeeping methodology, however this characterization can be misleading, as workplace organization goes beyond housekeeping (see discussion of "Seiton" below).
The key targets of 5S are workplace morale, safety and efficiency. The assertion of 5S is, by assigning everything a location, time is not wasted by looking for things. Additionally, it is quickly obvious when something is missing from its designated location. Advocates of 5S believe the benefits of this methodology come from deciding what should be kept, where it should be kept, and how it should be stored. This decision making process usually comes from a dialog about standardization which builds a clear understanding, between employees, of how work should be done. It also instills ownership of the process in each employee.
