INTRODUCTION 5S Is a simple but highly effective set of
techniques that remove waste from your work environment through better workplace organization, visual communication and general cleanliness.
The pillers of 5S are defined as Seiri, Seiton, Seiso, Sheketsu, and Shitsuke.
Because each of the five pillars begins with “S”, this method was appropriately names 5S.

5S PRINCIPLES Sort – Clearing the work area Any work area should only have the items needed to
perform the work in the area. All other items should be cleared (sorted out) from the work area.
Set In Order – Designating Locations Everything in the work area should have a place and
everything should be in its place. The needed items should be kept in the correct place to allow for easy and immediate retrieval.
Shine – Cleanliness and workplace appearance The third pillar of 5S helps to keep work areas, all
work surfaces and equipment clean and free from dirt, debris, oil, etc.
![Page 8: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/8.jpg)

5S PRINCIPLES Standardize : Everyone doing things the same
way Everyone in the work area and in the
organization must be involved in the 5S effort, creating best practices and then getting everyone to “copy” those best practices the same way, everywhere, and every time. Work area layouts and storage techniques should be standardized wherever possible.
Sustain : Ingraining the 5S’s into the culture SUSTAIN is the last pillar of 5S and drives the
organization to be disciplined in maintaining these new standards and procedures and in continuously improving the 5S state of the workplace.

WHEN TO IMPLIMENT 5S Space is crowded with parts and tools Unneeded items are stacked between
workers Excess inventory on the floor Excess items and machines make it
difficult to improve process flow Equipment is dirty and a collection point
for miscellaneous materials Needed equipment such as tools are
difficult to find
![Page 13: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/13.jpg)

SEIRI – SORT Seiri is distinguishing or sorting out between wanted and unwanted items in a place and removal of the unwanted such a place can be a shop floor, an office, a house or a hospital.
![Page 16: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/16.jpg)
16
HOW TO IMPLIMENT SEIRKI Some typical areas where Seiri might be applied include work in process, unnecessary tools, unused machinery, defective products, and paper and documents.
Separate needed items from unneeded items. Remove unneeded items from working areas Item never used : Discard Item not needed now : Store them. Remove all excess items from working areas,
including work pieces, supplies, personal items, tools instruments, and equipment.
![Page 17: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/17.jpg)
17
HOW TO IMPLEMENT SEIRI Use red tag to get rid of unneeded
items. Store items needed by most people in a
common storage area. Assign a person to organize and
manage the common storage area. Store items only needed by each
individual in his/her own working area. Organize working / Storage area.
![Page 18: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/18.jpg)
18
RED TAGGING The Red-Tagging Strategy is a simple method for
identifying potentially unneeded items in the factory, evaluating their usefulness, and dealing with them appropriately.
It is simply putting Red tags on items in Factory that need to be evaluated as being necessary or unnecessary.
An Item with Red-Tag is asking 3 Questions. Is this Item needed ? If it is needed, is it needed in this quantity ? If it is needed, does it need to be locate here ?
![Page 19: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/19.jpg)

THE CONCEPT OF 3 Mus Here are expressions of problems : Muda – Waste – Activity that does not
add value to the job – Non – value added, unnecessary, avoidable
Mura – Inconsistency – Not uniform in size, strength, ability, value, rank, number, etc.
Muri – Strain – Excessive exertion / tension, demand on one’s emotions

MUDA Things that do not help anything Things that are not profitable Unprofitable actions are…
Work procedures that make you stack or rearrange materials, parts, products or tools
Work that needs one or more steps Work that makes you wait Searching, Cleaning up messes, repairs,
tune ups, slow operations, sorting and inspections

MUDA – WASTE Questions to be asked to detect WASTE 5W - 1H What for ? (Purpose)
What is that ? What is it for ? What would happen if that operation was
eliminated ? What else should be done ?
Why ? (Necessity) Why is it necessary ? Why that way ? Why is that being done ?
![Page 66: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/66.jpg)
66
MUDA – WASTE 5 W – 1 H Where ? (Place)
Where is the location ? Why there ? Can it be changed ? Can it be combined at
one place ? When ? (Sequence)
Why at that time ? When it is reasonable ?
Who ? ( Operator) Who is that ? Why he does that open ? Are many people doing the same job ?

67
MUDA WASTE 5 W – 1 H How ? (Method)
Why is it being done this way ? Is that the best way to do it ? Can it be done another way ? How much will it cost ?
![Page 68: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/68.jpg)

PROBLEM IDENTIFICATION What is a problem ? It’s the deviation from the norm Difference between what’s expected &
what is actually occuring Reducing or eliminating the difference
between the two is solving the problem. All improvements start with the
perception of a problem as a deviation from the ideal.

KAIZEN CULTURE People are free to make mistakes. People should admit mistakes. Process-oriented thinking, along with result-
oriented. People work in a collaborative manner with mutual
trust. Emphasize what is wrong, rather than who. Make decisions with data, not ad-hoc. Subscribe to marketing concept (customer
concept). You are surrounded by mountains of treasures
(problems). Improvement starts from home. Never fail to standardize.

85
GOLDEN RULES FOR IMPROVEMENT Do not make an excuse. Think about how to do it, not how to
explain it. Don’t be afraid of trying, due to fear of
failure. Do it now. Do not seek perfection. 60% is good
enough to move forward. Try Try And try.
![Page 86: KAIZEN Updated 030507](https://reader034.vdocuments.net/reader034/viewer/2022042723/58724cb51a28ab852f8b604b/html5/thumbnails/86.jpg)
86
GOLDEN RULES FOR IMPROVEMENT Replace activities that do not contribute
to profits with ones that do. Time is the shadow of motion. Do not use money. Use your head. If you
cannot use your head, sweat it out. There is always room for improvement. Management is starting with planning
and comparing it with results (PDCA cycle).
