What is 5S?
1. 5S is a house-keeping technique which is applied to
enhance productivity and safety in any enterprise
2. Developed by the Japanese
3. Helps Create a Better Working Environment and a
Consistently High Quality Process
4. It is usually the first Lean Management technique
implemented in any enterprise

5S - Background
• Since the early 80’s Japanese industries widely
practiced 5S as a powerful technique to improve
productivity and quality
• Today, 5 S is used worldwide to prepare the ground
for improvement
©
6
Discovery of 5S
• In the 1980’s, researchers started studying the secret
of success of Japanese manufacturing companies
• 5S turned out to be the most impressive "secret"
• The factories were so well organized that abnormal
situations were readily apparent
• Equipments were so clean and well maintained that
any problem such as a loose bolt or leaking oil could
be easily seen
• This passion of cleanliness and orderliness became a
hallmark of Japanese organizations

Idea behind 5S
In order to achieve high levels
of
Quality,
Safety
and
Productivity, workers must
have a conducive working
environment
©
8
Advantages of 5S
• If tools and materials are conveniently located in
uncluttered work areas:
▫ Operators spend less time looking for items
▫ Higher workstation efficiency, a fundamental goal in
mass production
• A clean and tidy workplace leads to greater well being
and increased motivation
• Company image improves

Advantages of 5S
• Health and Safety is ensured
• Machine maintenance
• Quality
• Productivity
• Lean Manufacturing
©
10
Advantages of 5S
• Results in a place easier to manage
• Smooth working
No Obstruction
• N0 deviation or problem arises because everyone knows
where the things are supposed to be

11
Advantages of 5S
• Time saving
• Quick retrieval
• Accidents and mistakes minimized
• Increases Space
• Creates workplace ownership
©
12
Advantages of 5S
• Foundation of all QC tools
▫ Continuous Quality improvement
▫ Enables Lean Manufacturing
▫ Kindergarten of Quality tools and techniques
• Enables Visual Management
▫ In a clean and tidy working environment it is easier to
spot problems
©

- 7. 08-01-2014
13
Kindergarten of all QC tools
• 5S is the starting point of all the QC tools
• Could be said as the pre-requisite of all QC tools
▫ If an enterprise is embarking on the Lean Management
journey to improve the quality of production or
process, it must definitely have 5S implemented
©
14
Why do 5S?
©
7
- 8. 08-01-2014
15
Levels of workplace organization
• Following the 5 S principles and reducing waste
• Extending the 5 S concept to include ergonomics –
interaction of workers with their environment
• Extending the 5 S concept to include aesthetics
– how to maintain the look and feel of the working
place
• Educating others
©
16
Elements of 5S
• 5S comprises of 5 Simple steps:
1. SEIRI ------------- Sorting out
2. SEITON ---------- Setting in Order, Systematic
Arrangement
3. SEISO ------------ Shining, Spic and Span
4. SEIKETSU ------- Standardization
5. SHITSUKE ------- Sustain, Self Discipline
©

- 9. 08-01-2014

Step 1 – SORTING (SEIRI)
• Objective: Saving and Recovering Space
• What do we intend to do?
▫ Segregate necessary from un-necessary and throw
away what is not required at all
▫ Decide on a frequency of sorting
©
18
Step 1 - SORTING (SEIRI)
1. Decide what you need
2. Remove unnecessary clutter
3. All tools, gauges, materials, classified and then
stored
4. Remove items which are broken, unusable or only
occasionally used
©
9
- 10. 08-01-2014
19
Red-tag technique
1. Give staff Red Labels
2. Ask staff to go through every item in the workplace
3. Ask if needed and those that are needed, in what
quantity
4. If not needed, then RED TAG it
5. Store in the RED TAG area
©
20
Red-tag technique
For the suspected/not-sure items:
6. Place the suspected items in the RED TAG area for
one week
7. Allow the staff to re-evaluate the needed items
8. At the end of week, those items that are needed and
frequently used should be returned

Step 2 – Setting in Order (SEITON)
• Objective: Minimize search time and errors
• What do we intend to do?
▫ Analyze why getting things out and putting them back
takes so long
▫ Put things in ORDER
©
26
Step 2 – Setting in Order (SEITON)
•
A rational, orderly and methodical arrangement of all
items we use, re-work or write off
•
Once all un-needed items have been eliminated, it is
needed to manage the remaining useful items
•
Organise layout of tools and equipment
1. Mark Designated locations
2. Use tapes and labels
3. Ensure everything is available as it is needed and at
the “point of use”
©
13
- 14. 08-01-2014
27
Step 2 – Setting in Order (SEITON)
Workplace Checkpoints
1. Positions of aisles and storage places clearly marked?
2. Tools classified and stored by frequency of use?
3. Pallets stacked correctly?
4. Safety equipment easily accessible?
5. Floors in good condition?

An example of how 5S implementation can be evaluated
using Binary and % ratings*
Evaluating Seiri (Sort) stage:
1. Material availability Give 1 mark if material is fully available or
give 0 marks if material is not fully available
2. Defective goods If there are X items which contains Y items as
defective Then the marks will be Fraction of fine goods = [1{Y/X}]
3. Operating condition Give 1 mark if operating condition is under
control and give 0 marks if operating condition is not under
control.

An example of how 5S implementation can be evaluated
using Binary and % ratings*
Evaluating Seiri (Sort) stage:
4. Relative information about working condition, process
guidelines, tools information, material information etc., is also
important for Seiri rating. Give 1 mark for full information and
give 0 marks for partial information.
5. Elimination of waste Let total N no of wast are listed but only M
were eliminated the marks of elimination process will be
Fraction of waste elimination = [1- {M/N}]

Ratings
An example of how 5S implementation can be evaluated
using Binary and % ratings*
Evaluating Seiri (Sort) stage:
• Now add all five marks and get total rating of Seiri out of 5. If the
Seiri system will get less than 3 marks then do the arrangement
again
• Do this for all the stages and calculate the average 5S rating
* Based on a paper on Performance Improvement through 5S in Small Scale Industry: A case study by P. M. Rojasra, M. N.

Group Activity
We will work on a hypothetical scenario to implement 5S
1. Divide in groups of 6 each.
2. Think of any activity which you engage in regularly. For
example: Working in Office, Working in kitchen, Working
on your computer, Running a plant etc.
3. Discuss how you can implement 5S in these activities (Use
flip charts)
4. Also mention how you will evaluate the improvements after
using the 5S technique
5. Present to the gathering

Visual Management
©
30
- 31. 08-01-2014
61
What is Visual Management
A technique where control of an activity or process is made
easier or more effective by deliberate use of visual signals.
They give feedback to an operator about how a process is working and
can alert the operator to act
Usually used in 5S, but can be implemented with any process
improvement initiative
Visual Controls can also include audible signals
The 3 beeps from your microwave once your food has finished cooking
©
62
Goals of Visual Management
The goal of visual controls is to make a process:
Self-explaining
Scoreboard at a baseball game
Self-ordering
RO system
Self-regulating
Traffic lights
Self-improving
Facilitate corrections in MS Word or email
©
31
- 32. 08-01-2014
63
The idea behind Visual Management
When someone walks into the workplace they should
be able to determine:
▫
▫
▫
▫
What the process is,
Who the customers and suppliers are,
What the deliverables are,
Where and what resources are being used in the
process,
▫ The health of the process,
▫ That there is an effective measurement system in place.

▫
▫
Observe, don’t just ask
The steps are defined by the designer
2. Break operations into observable segments
3. Study machine capacity, cycle times, and changeover times
4. Look for value-added and non-value-added elements

•
Minimize motion
Avoid unnatural postures and movements
Avoid sharp turns in motion
Make moves easy to perform without much concentration
Use hands and forearms instead of upper arms and shoulders
for light work
Minimize lifting
•
