5S
is a workplace organization method that puts a work area in order
and sustains that order, so that any waste can continue to be
identified and eliminated. This program can be used to supplement
the Lean Enterprise system.
5 S is short
for the words: Sort, Straighten, Shine, Standardize, and Sustain
(which are based on 5 Japanese words that describe the standardized
organization and are listed below). Another “S” that
is often added to the 5S is Safety.
Seiri - Tidiness, Organization
Refers
to the practice of sorting through all the tools, materials,
and equipment in the work area and keeping only essential
items. Everything else is stored or discarded. This leads
to fewer hazards and less clutter to interfere with productive
work.
Seiton
- Orderliness
Focuses
on the need for an orderly workplace. Tools, equipment, and
materials must be systematically arranged for the easiest
and most efficient access. There must be a place for everything,
and everything must be in its place.
Seiso - Cleanliness
It is
essential keep the workplace clean and neat. Cleaning in Japanese
companies is a daily activity (at the end of each shift, the
work area is cleaned up and everything is put back in its
place).
Seiketsu - Standards
The workplace
environment needs to be consistent and controlled. Basic housekeeping
standards apply everywhere in the facility, and everyone knows
exactly what his or her responsibilities are.
Housekeeping duties are part of regular work routines.
Shitsuke - Sustain Discipline
The standards
must be maintained to keep the workplace in order. These rules
keep the facility safe and productive when they are enforced..
5S is used
in conjunction with other Lean concepts such as Total Preventative
Maintenance (TPM) and Cellular Layout. The 5S discipline requires
clearing out things which are not needed in order to make it easier
to obtain the tools and materials that are needed in the production
process, thus making the workplace more efficient and productive.
