What is 5S n A systema<zed approach to organized workplace, keeping rules and standards, and maintaining the discipline needed for an excellent opera<on
n 5S is a methodology developed by the Japanese for achieving a visual, safe, pleasant, and produc<ve workplace
n Each “S” represents a Japanese word that describes the basic but very important aspects of this universal approach – the five pillars
n These 5 pillars “carry” the improvement ac<vi<es forward

Pleasant workplace?
What appears to be the problem?
“Normal” behaviour People leave trash People tolerate it No one stops to pick it up
5
“Normal” behaviour People leave trash Some do not tolerate it , pick it up
Desirable behaviour People do not leave trash People do not tolerate it Everyone picks it up

Common workplace issues
Unorganized workplace
Dirty / Unsafe areas
Crowded work areas

The approach (overview) n Step by step! n Overview of the plant
¨ In large or medium companies – select pilot area ¨ Focus on the critical areas ¨ Take photos (Before and After album)
n Create in house team – few motivated persons n Define areas and responsible persons n Run specific campaigns and monitor results n Show case success, motivate the remaining persons
Key 1: Seiri (Sor<ng out)
Dis<nguishing between what is needed and what is not needed
Eliminate what is not needed
8
Movie clip
But how to do Seiri?
Use Throw
When in doubt – throw it out!
9
n Differen<ate the necessary and the unnecessary ¨ Mark the unnecessary items with a “red tag”
n Ask 4 ques<ons ¨ Is this item needed for our current work/produc<on ? ¨ In what quan<ty ? (we do not need too many)
¨ Where should it be located ? (if seldom used, move to warehouse) ¨ Is this item func<oning properly and safe ? (if not, replace)
n Dispose of the unnecessary ¨ Use a “red tag holding area” for items you are unsure of or can not dispose of
immediately
1S: Sort – steps to follow
Red Tag Technique n Using a red tag to determine what is s<ll needed and
what is not, e.g. red tag anything that is not needed for the next 3 to 6 months
n Communicate this informa<on to everyone who will be involved in the exercise
n Set-‐up a temporary Red Tag Holding Area n Aaach Red Tags to all unneeded items. n Remove all items and store in the holding area. n Sort thru unneeded items and dispose of them (those
that are truly unneeded) n Con<nue Red Tagging Regularly
10
Red Tag Technique
Red Tag Technique 1. STARTING POINT
PARTICIPANTS: Manufacturing/Materials/Management
PERIOD: 1 – 2 months
OBJECTIVE: Ensure workers never hide unnecessary items
11
Red Tag Technique 2. DISTINGUISHING RED TAG ITEMS
STOCK: Raw Materials/Parts/Products
FACILITIES: Machines/Equipment/Jigs and Tools/ Molds/Carts/Desks
SPACES: Floor/Shelves/Storage
Red Tag Technique 3. FIXING RED TAG STANDARDS
Clarify standards for unnecessary items:
e.g.: “No Tag” for items to be used within the next month; “Tag On” for items not to be used within the next month.
12
Red Tag Technique 4. DESIGN OF RED TAGS
• A4 or A5 Size Red Paper
• Include name of item, quan4ty, reasons, etc.
Red Tag Technique 5. ATTACHING RED TAGS
• Don’t let people directly concerned a^ach them.
• Listen to no excuses.
• Be strict about it.
• A^ach tags to any doub_ul item.
• The number of tags indicate checking efficiency and not failure.
13
Red Tag Technique 6. DEALING WITH RED TAG ITEMS AND EVALUATION
STOCK: List unnecessary stock by dividing them as dead stock and sleeping stock.
EQUIPMENT: Move or reject any items which hinder the implementa4on of 5S ac4vi4es.
Red Tag (Sort) Checkpoints n STOCK: Raw Materials, Parts, Work-‐In-‐Progress,
Component Parts, Finished Products.
n FACILITIES: Machines, Equipment, Jigs, Tools, Cuhng Tools, Molds, Fihngs, Carts,
Pallets, Liis, Working Tables, Vehicles, Desks, Chairs.
n LOCATIONS: Floors, Shelves, Rooms. n DOCUMENTS: No<ces, Circulars, Minutes, Office
Reports, Drais, Quota<ons, Memos, Numerical Data.
n MACHINES: Copy Machines, Personal Computers, Printers, Fax Machines, Shredders.
14
Deciding the Standards for Red Tags
• “It’s wasteful to throw things away!”
• “It was so much trouble for me to make these things!”
• “We might possibly use these later!”
• “Shouldn’t workers place the red tags?” NO!
Red Tag (Sort) Checkpoints • PERSON RESPONSIBLE:
Raw Materials, Parts, Work-‐In-‐Progress, Component Parts, Finished Products.
• ATTACHMENT PERIODS: 1 to 2 Days, as necessary.
• ATTITUDE: -‐ Workers will believe everything is necessary! -‐ Look at situa<on with a very cri<cal ahtude -‐ Be a Red Tag advocate!

Key 2: Seiton (Systema<c Arrangement)
"A Place For Everything and Everything In Its Place"
But how does it help?

2S – Seiton Count these stars Now count these stars
What is Seiton? n It is an ac<on to put every necessary items in good order n A ra<onal, orderly and methodical arrangement of all items we use, re-‐work, store
n Done with the objec<ve of minimising search <me

How to do Seiton? n Use ra<onal layout of machines, equipment and cabinets n Place frequently use items at point of use
Frequency of use
Hourly, daily, weekly
Weekly, monthly
Quarterly
Storage place
Close to machine
In work place, but away from machine
In store area
21
How to do Seiton? n Use rational layout of machines, equipment and cabinets n Place frequently use items at point of use n Pre-fix a place for everything and place everything in its
place with pre-determined quantity n Use labels and colour codes to identify items n Use index for files, records and drawings n Plan storage to retrieve with ease n Separate mixed up items in cabinets and organise them
to be self explanatory through identification aids n Establish visual controls for checking missing items
22
4 signs of good Signs 2S 1. LOCATION : Outline, Arrows, Separators 2. IDENTITY : Descrip<on -‐ “What is it?” 3. QUANTITY : How many should be here 4. INSTRUCTION : What do you want me to do

Key 3: Seiso (Cleanliness)
“Cleaning Is Inspection"
30
What does it mean? n Keeping everything swept and clean n Understanding how to prevent things from gehng dirty and ensuring best condi<ons
n Done with the objec<ve of inspec<ng for problems and taking quick correc<ve ac<on
How to do 3S? n Elimina<ng all forms of dirt n Finding ways to keep the workplace clean n Adop<ng cleaning as a form of inspec<on n Making cleaning part of everyday work
31
The Shine concept
• Clean to Inspect • Inspect to Detect • Detect to Correct • Correct to Perfect
Three phrases of Shine
n Daily Shine: Making things clean ¨ Sweep, mop, and wipe floors, walkways, and shelves ¨ Scrub away grit and dirt that has become caked onto oily
equipment surfaces
n Shine Inspections: Using your senses ¨ Pay close attention not only to the main section of each machine
but also to its moving parts and drive chain ¨ Check for proper amounts of oil, air, ventilation, etc.
n Shine Maintenance: Making improvements ¨ If the operator is able to quickly fix or improve the slight defect, this
should be considered part of the operator’s Shine Inspection duties ¨ If the operator finds it difficult to fix or improve the defect quickly, he
should seek help
32

Key 4: Seiketsu (Standardize)
• Check • Standardize • Maintain • Monitor • Improve
What? • Rules of Placement of Materials • Work Procedure • Set up Procedure • Tool Change Procedure • Daily, Weekly and Monthly PM • Displays • FML, Control Charts
What does Standardise mean?
n Maintain and monitor the first three keys n Standardized Clean-‐up, the 4th Key, differs from Sort, Store, and Shine ¨ because it refers not to an ac<vity but to a standardized state or condi<on at
a certain point in <me ¨ Specifically, we may define it as “the state that exists when the first 3 keys
are properly maintained n Standardizing achieves a state of cleanliness which allows you to immediately tell the difference between normality and abnormality
34
How to proceed? n Develop a standard opera<ng procedure for all ac<vi<es n Implement 5W1H
¨ Who is responsible for the task? ¨ What equipment, tools, or materials are necessary? ¨ Where will the ac<vity take place? ¨ How will the ac<vity be implemented? ¨ Why is the ac<vity necessary? ¨ When will the ac<vity be done?
Examples of work standard

Key 5: Shitshuke (Self-‐Discipline)
Monitor and Follow Daily Work Management
36
What does it mean? n A condi<on where all employees prac<ce the 4S spontaneously and willingly as a way of life (culture)
How to proceed? n Conduct periodic audits / site patrols n Provide training n Give recogni<on and incen<ves n Always measure the benefits of 5S
