5S Meaning

    ➤ [1] 1st S - Seiri or Sort:

    → The first step is Sort in this Methodology.
    → "Sorting" means to sort everything in each work area that we need and what we do not need? 
    → Sort means removing unnecessary items or materials from a workspace.
    → Keep only what is actually required every day from the workspace.
     Materials, equipment, instruments or any items that are not frequently used should be moved to a separate, common storage area called Red Tag Zone.
      Items that are not used should be removed or recycled.
    → Please do not keep anything in your workplace just because it might be used in the future.
    → The whole team should spend a few hours going through the entire area (inside cabinets, under and behind machines.. Everywhere !!!)
    → All obvious scrap should be put in the scrap area / Bin
    → All unidentified items should be put in the “Red tag”/ quarantine area.
    → Only items that are required should remain.


    ➤ Steps for Sorting:

        1. Cleaning
        2. Classifying
        3. Assign Responsibility
        4. Red Tagging of unnecessary things
        5Recycling or Reassignment of things arrived in Red Tag Zone.

    ➤ [2] 2nd Seiton or Set In Order:

    → Set in order is for organizing the items or materials at the workplace.     
     “ Define Place for Everything and Put Everything in its place”
     We can use an organized workplace more efficiently and effectively
    → To arrange all necessary items for the economy of movement.
    → Put things as per the frequency of use.
    → Provide safe storage – heavy items at a low level, light items at height.
    → If any item is missing then we can easily find out it


    ➤ Basic Principles of Set in Order:

    → The things that are used very frequently should be kept nearer to where they are used.
    → Items that are used very few times should be kept far compare to frequently used things.
    → After completion of work keep things in its defined place.
    → If several things are used together, then store them together.
    → For example, a welding rod is used with a welding machine then both should be kept together.
    → Store things in place where people can easily find it.
    → Identify all items (including fixtures, gauges, tools, jigs, molds, etc.) and mark identification symbols on them so we can easily identify and return them to their identified storage location.

     After Sort and Set In Order, the workplace requires regular cleaning.
    → Shine or cleaning is used for regular cleaning of the workplace, tools, and equipment

    → The best approach is that those who work in a workplace is also responsible for cleaning that area.

    → What needs to be cleared and where
    → When it will be done
    → How is it to be done
    → Required tools for cleaning

    ➤ [4] 4th S Seiketsu or Standardize:

    → After completion of Sort, Set In Order and Shine or Clean, Standardize will come.
    → Standardize means documenting all necessary processes or activities.
    → In Standardize we can turn Good Practices into Good Habits.
    → By developing standards for process, all person knows what to do, how to do, when to do and where to do, etc..

     It will help them to remember the new standards and it encourages them to do the same.
     We can use labels, symbols, posters, and banners for standardization.


    ➥ (A) How do we Standardise?

    → Document standard ways of working (SOPs)
    → Standardize labeling, signage, and Flow
    → Audits


    ➥ (B) Standard Work:

    → Document the current agreed way of doing a process

    → Independent audit of an area
    → Capture current state – Use color photographs
    → Create simple audit sheets – with a score
    → Conduct audits

    ➤ [5] 5th S Shitsuke or Sustain:

    → Sustain needs to maintain 5S within the factory or work pace.
    → Keep a record of progress with evaluations, communication, and training related activity.
