Why 5S is Important We feel good when the place where we work every day is clean We can avoid the hassle of searching for things We can eliminate time wasted in searching We can reduce our defect rate by detecting problems earlier Preventive maintenance will be better because equipment inspection will be easier We can reduce the amount of machinery down time We can create more usable space
SEIRI – Sorting out / Clearing up “ Clearing up is to Discard ” Separate needed items from unneeded items. Keep only the necessary in work area Keep in a distant storage area less frequently used items Unneeded items are to be discarded Store items needed by most people in a common storage area Should not have sentimental attachments Use red tag to get rid of unneeded items
Ideas for using Red tags No Tag : Used at least once in every 2 days [Don’t remove the item form its place of use]

Type C : Used once in a year or less frequently [Consider storing it outside or move it off-site]
The red tag asks the following: Is the item needed ?
Type D : No longer needed
If it is needed how many do we need ?
[Remove : Sell, Return, Donate or Scrap] If it is needed is it in the correct location ?
How to Implement Decide whether it is necessary or not. Attach “Red tag” if it is unnecessary. Move as per the instruction in red tag Register Red tag, Review & Record the disposal. Identify a “Red-Tag” area to move surplus materials. These materials may be useful for other departments. Others should check whether anything will serve the purpose before ordering for new. Take fixed point photo Before & After
SEITON – Set in Order “ A Place for everything and every thing in its place ” Decide “Where” to place & “How” to place Place things in such a way that they can be easily reached whenever needed. Systematic arrangement for the most efficient and effective retrieval. Arrange items such that - Easy to find, Easy to use & Easy to put away. Use visual controls [Labeling, sign boards, color codes, outlines etc.,] Ensure FIFO
How to Implement Place tools close to the point of use. Use rack / shelf instead of stacking. Use small bins to organize small items. Clearly label each item and its storage area. Use see-through cover for visibility. Ensure everything is available as it is needed and at the “point of use” Design locating slots to keep things in its place Establish storage procedures & Display instructions
SEISO – Shine “ Cleaning is Inspection” Keep things clean, No trash or dirt in the workplace Determine “who” and communicate “when”. Emphasize the maintenance of a clean workplace. Sweep, dust, polish and paint Continual cleaning of a work area is best approach. Areas which are not normally seen should also be cleaned. Identify and eliminate causes of dirt and grime – focus on removing the need to clean.
SEISO – Shine Use dust collecting covers or trays Investigate the causes for dirtiness and eliminate at the source Cleanliness ensures a more comfortable and safe working place. Lead to visibility so as to reduce search time. Ensures a higher quality of work and products helpful to notice damages on equipment such as leaks, breakage and misalignment. These minor damages, if left unattended, could lead to equipment failure and loss of production
How to Implement Organise introduction meeting and explain clear about the objective Identify the root cause for the generation of dirt and arrest Prepare a cleaning schedule by answering : Where to clean

Area
What to clean
–
Item
When to clean
-

SEIKETSU – Standardise “ Standardising is to keep Clean” Maintain and monitor the first 3 categories Make it as a habit. Determine “who” is responsible for “what”. Have an easy-to-follow standards and develop a structure to support it. Promote visual controls & Install team boards in shop floor Regularly audit using checklists and measures of housekeeping.
