6S
To Create a Workplace suited for Visual Control and Lean
Production
The Six Ss Is not Six Sigma
A highly disciplined process that focuses on developing and delivering near-perfect products and services
6S is Sort, Straighten, Shine (Scrub), Safety, Standardize, Sustain 5-S… in Japanese factories Focus: orderliness 6th S added in some US companies… Safety Combines orderliness with safety / ergo Overall intention: CLEAN, SAFE, ORDERLY First step on Lean Journey
Visual Factory/Office
1st Level: See the Shop/Office Basic 6S 90% never get beyond this point
2nd Level: See the work In 5 Seconds, can you see what’s
going on?
6S Think of 6-S as a repeating action
sequence: 1: SORT OUT - get rid of what’s not needed 2: STRAIGHTEN - organize what belongs 3: SCRUB - clean up, see and solve
problems 4: SAFETY - make the work area safe 5: STANDARDIZE - assign tasks, track
visually 6: SUSTAIN - keep it up (audit and insist)
Remember… This applies to all areas (value-adding and
administrative) Basic "6-S” is part of establishing any cell
Sort GET RID OF WHAT’S NOT NEEDED
Start with a red tag campaign Tag everything that looks disorderly or
unsafe Be ruthless (90% of the time you'll be OK,
you'll get over the 10%) If in doubt throw it out If still in doubt, send it to a “red tag area”
for resolution You should be removing truckloads of
items… be tough (sometimes you’ll need to ask for forgiveness later!)
Straighten ORGANIZE WHAT BELONGS
Create a place for everything Meet with shop/office personnel on what
should be where Deal with the open red tags from the
"Sort Out" step: Organize parts and material Resolve things you were afraid to throw
out Write off or sell off obsolete materials
Straighten

Straighten
Scrub CLEAN UP, SEE AND SOLVE PROBLEMS
Make the work area absolutely clean Clean everything (equipment, floors,
walls…) Paint everything (equipment, floors, walls…) Look for problems…
Leaks? Loose or missing items Unsafe conditions Causes of messes or problems… Quality issues
Solve problems (root cause), take corrective action (prevent)
Scrub
Safety MAKE THE WORKPLACE SAFER
Look for unsafe conditions Look for potential for unsafe acts Look for difficult tasks (are they
ergonomic?) Try the jobs yourself… where could
you get hurt? List the opportunities Resolve them
Put creativity before capital and put safety first!!!
Safety
Standardize ASSIGN TASKS AND MANAGE
VISUALLY Who will do what to keep the area
clean, safe and orderly? Agree on daily and weekly tasks Establish a visual management
system for these tasks
Can you tell at a glance if the tasks have been done?
Standardize
Sustain KEEP IT UP (AUDIT AND INSIST)
Develop audit checklists for office and for shop floor
Assign the audit role to someone outside the area
Track the audit results (a bit of friendly competition?)
Hold yourselves accountable for sustaining
Sustain - Maintain The Gains Create checklist for
entire area & all items within the area
Use checklist daily or weekly as appropriate
Once a year have Examiners perform independent review
Fix and clean daily Continue to train &
heighten awareness Remember you are
World Class! Act like it.
Sustain - 6S Scorecard0 = No evidence that 6S is being
considered for implementation1 = Some evidence of 6S being
started 2 = 6S is partially implemented
(some gains are evident)3 = 6S has been implemented but
not self-sustaining4 = 6S has been implemented & is
self-sustaining (standard throughout)
5 = 6S is entrenched; efforts have resulted in high achievements
6 = “Out-of-the-box”; Area is doing extraordinary things, above & beyond the norm
Sustain - 6S Scorecard0 – 20 = Some organization,
needs much improvement
21 – 40 = Signs of 6S in place, good organization, needs more time to mature
41 – 60 = 6S implemented, signs of maturing, not self-sustaining
61 – 80 = 6S implemented, system is self-sustaining
81 – 100 = 6S is entrenched with high achievements
100+ = Extraordinary, over-and-above, “outside-the-box”
Visual Management Make normal / abnormal conditions
obvious with Floor and surface marking Shadow boxes Samples Visual indicators Obstacle height limits Lights and sounds Arrows, zones, stickers Scoreboards Labels and tags
For Shops Remove unnecessary items All cleaning material stored in a neat manner Floors clean of debris, oil and dirt Bulletin boards updated, straight and neat Easy access to emergency equipment, highly visible Items on floors are in clearly marked areas Aisles are clear and kept free of material Storage of boxes is square, neat, orderly Machines, tools, equipment kept clean Nothing on top of machines or cabinets Documents and binders stored in a neat manner Tools, jigs, fixtures, details are labeled, shadowed,

outside cubicle/office Office equipment and furniture is functional and in good repair Paper, cabinets, and bins squared up, centered and at right
angles, PC wiring is routed and secured/clamped Desks, surfaces, cabinets, chairs cleaned weekly Nothing on top of overheads or cabinets, nothing leaning
