5S
If we do not do 5S, we can’t do any
other work efficiently. They are
features which are common to all
places and are the indicators of
how well an organization is
functioning.

SEIRI = Sorting
Meaning
Distinguish between necessary and unnecessary
items and eliminate the unnecessary items
Activity
Establish a criteria for eliminating unwanted items
Eliminate unwanted items either by disposing
them or by relocating them.
Success
Indicator
Area saved or percentage of space available
6
SEIRI = Sorting
Japanese Meaning :
The Japanese
meaning of “Seiri” is to straighten and
contain.
- Get rid of waste and put it in order according
to rules
OTHER JAPANESE MEANINGS farmland cultivation, Make an orderly system
and straighten
7
Seiri = Sorting
What is unnecessary
1. Item is not needed
2. Item is needed however quantity in stock is more
than what is needed for consumption in near
future

visual management
45
Seiketsu = Standardization
• It has been estimated by scientific
study that 60% of all human activities
starts with sight
• 5S is easy to do once.It is consistency
that is difficult. That is why Visual
Management is so important, so that
everybody will know that there is
some problem. Visual Management
46

guidelines.
To maintain DISCIPLINE, we need
to practice and repeat until it
