5S is a technique for organizing a workplace, especially a shared
workplace like a shop floor or an office space. It’s sometimes
referred to as a housekeeping method but this description can
be misleading because organizing a workplace goes beyond housekeeping.
The key targets of 5S are workplace morale and efficiency. The
point of 5 S is, to assign everything a location, time is not wasted
by looking for items. It is quickly apparent when something is
missing from its designated location. 5S advocates believe the
benefits of this style comes from deciding what should be kept,
where it should be kept, and how it should be stored.

A very important part of 5S and “standardized cleanup”
is Seiton. Seiton is often misunderstood, perhaps due to efforts
to translate into an English word beginning with S such as sort
or straighten. The key concept here is to order items or activities
in a manner to promote work flow. For example, tools should be
kept at the point of use, workers should not have to repetitively
bend to access materials, flow paths can be altered to improve
efficiency.
