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.
COMMON MIND SETS… Its an additional burden. Too busy to do 5S activities. Why clean it? It will get dirty again We cannot change the existing setup. More work pressure – No time for these things 5S means cleaning up the desk
SEIRI = Sorting – Just in Case to “Just-in-Time”
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 Area saved or percentage of space available Indicator
SEIRI = Sorting – Fight with habits
SEIRI = Sorting 3 Categories
√ - Item Required X – Item Not Required ?–

Activity
- Innovative visual management - Color coding - Early detection of problem and early action
Success Indicator
Increase in 5S indicator
SEIKETSU = Standardization Tools used for analysis : MTTR MTBF OEE
Seiketsu = Standardization • Regularizing 5S activities so that abnormalities are revealed •Make it easy for everyone to identify the state of normal or abnormal condition • For maintaining previous 3S, deploy visual management
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
Seiketsu = Standardization What visual control communicates ? It grabs one or more of our senses in order to • • • •
Alert us to an abnormality Help us recover quickly Promote adherence and prevention Enable successful self management
Seiketsu = Standardization Some methods for visual communication ⇒ ⇒ ⇒ ⇒ ⇒ ⇒ ⇒
Color coding Use of Labels Danger alerts Indication where things should be put Directional arrows/ marks Transparent covers Performance indicators
Seiketsu = Standardization Some methods for visual communication Labels ⇒ Precision management labels ⇒ Inspection labels ⇒ Temperature labels ⇒ Responsibility photos
Seiketsu = Standardization Points to remember in making visual c control tools 1. Make them easy to see from distance 2. Put the display on the things 3. Everyone can tell what is right and what is wrong 4. Anybody can follow them and make necessary corrections easily 5. Work place should look brighter & orderly
Seiketsu = Standardization Some everyday visual management examples ♦ Traffic signal ♦ Zebra crossing ♦ In car - Petrol indicator - Speed indicator ♦ Direction arrows ♦ Electric danger sign ♦ Toilet
Seiketsu = Standardization Some visual communication signs
SHITSUKE = Self Discipline Meaning
Every one sticks to the rule and makes it a habit
Activity
- Participation of everyone in developing good habits - Regular audits and aiming for higher level
Success Indicator
High employee morale Involvement of all people
SHITSUKE = Self Discipline Activities : 5S Committee 5S Training 5S Competition / evaluation 5S Month Posters , Literature etc.
Shitsuke = Self Discipline
We need everyone to maintain 5S guidelines. To maintain DISCIPLINE, we need to practice and repeat until it becomes a way of life. Discipline is the Core of 5S
Shitsuke = Self Discipline
Discipline means making a steady habit of properly maintaining correct procedure. procedure Time and effort involved in establishing proper arrangement and orderliness will be in vain if we do not have discipline to maintain it.
Shitsuke = Self Discipline
Pledge
It shall be my constant effort to maintain my workplace in good order by Assigning a place for everything & keeping everything in its place Sorting out unwanted material periodically & discarding them Keeping my work area neat & clean everyday
