| The 5 S's stand for Sort (Seiri), Straighten (Seiton), Shine (Seiso), Standardize (Seiketsu) and Sustain (Shitsuke). |
Sort (arrangement) - eliminate all unnecessary items in the work area. This
includes ensuring you have the correct tools for the job which means adding equipment
that is required. The problem of sharing a tool creates the "search and retrieve" waste of time. |
Set in Order (straighten) - organize the work area so that
"Everything has a place and everything in it's place."
Shadow boards are commonly used. Keep commonly used tools close to the work
area and lesser used tools on the shadowboard. Eliminate drawers and cupboards - it is a
waste of time to open and close them. |
Shine (act of cleaning) - clean the work area. This eliminates possible
safety hazards and creates a better work environment. |
Standardize (Make Rules) - now that the three previous elements are in place, make
the revised work area the standard. This also applies to the work method or procedure.
Standardizing the way you process or assemble the product so that everybody performs the
operation the same way is an essential step in getting Lean. It provides a verifiable way of
producing product with the same cycle time and quality which ultimately helps in balancing the production line. |
Sustain (discipline, manner) - the discipline to maintain the improvements and
continue to improve. This element has proven to be the hardest of the five elements.
Focus on maintaining any revisions and continue to improve without slipping back into old habits.
Regularly scheduled Kaizen blitzes help in maintaining changes. |
