also called FISHBONE DIAGRAM (afterits shape, or Ishikawa Diagram; afterits inventor

ICQUALITY TOOLS
CAUSE AND EFFECT DIAGRAMBENEFITS:
breaks problems down into bite-size piecesto find the root cause
fosters teamwork
common understanding of factorscausing the problem
SO
FTW

ICQUALITY TOOLS
CHECK SHEETSrecording table matrix, designed bythe user to facilitate the recording &interpretation of test results
collect data in a systematic &organized manner
BENEFITS:
determine source of problem
facilitate classification of data

ICQUALITY TOOLS
CONTROL CHARTvisual presentation of comparisonbetween actual performance &pre-determined control limits
predict if process is “in control”or “out of control”
BENEFITS:
distinguish between specific,identifiable causes of variation

FLOWCHARTvisual illustration of the sequence ofoperations required to complete a task
identify process improvements
BENEFITS:
understand the process
shows duplicated efforts

HISTOGRAMa graph of side-by-side vertical barsrepresenting a frequency distribution
allows user to understand at a glancethe variation that exist in a process

PARETO CHARTa frequency chart in descendingorder; the bars are usually associatedwith problems
tells user what to work on first
BENEFITS:
SCATTER DIAGRAMdisplays the relationship betweentwo variables; the quality characteristicsand a factor that might be driving it
it helps user identify and testprobable causes

SHITSUKE
(SUSTAINING)sustaining the discipline
refers to maintaining and reviewing standards. Once the previous 4S have been established, they become the new way to operate
maintain the focus on this new way of operating
do not allow a gradual decline back to the old way of operating
5S METHODOLOGY
ADVANTAGES & DISADVANTAGES

GYADVANTAGES & DISADVANTAGES
SEIRI(SORTING)
ADVANTAGES:deal with the causes of defects, noise and leakstreat defects, leaks and breakages
aim for the policy of “one is best” – one location file, one-stop service for customers, etc.
DISADVANTAGES:slow implementation approach – boilingthe frog approach
5S

GYADVANTAGES & DISADVANTAGES
SEITON(STRAIGHTENING OR SETTING IN ORDER)
ADVANTAGES:functional placement of parts, tools and materials
quick (30-second) and easy retrieval of documents, parts and tools
neat and easy-to-read notice boards (with special attention to removal of old and obsolete boards)
filing standards and controls
zoning and placement marks
arrangement for first-in, first out

SEISO(SWEEP / SHINE)ADVANTAGES:
assigning individual cleaning responsibilities
adopting simple methods for cleaningand inspection
regular cleaning activities
cleaning even the less-noticed places

SEIKETSU
(STANDARDIZING)ADVANTAGES:
certification of inspections using labels, tags, etc.,
“danger" warning marks and signs
colour coding of files, pipes and containers
responsibility labels
preventing noise and vibrations
directional markings on pipes and gangways
DISADVANTAGES:lack of Management Support – do as I say, not as I do

SHITSUKE
(SUSTAINING)
ADVANTAGES:following safety rules
DISADVANTAGES:
executing individual responsibilities
good communication practices
practicing dealing with emergencies
checking and following "5-S" practices always
misunderstanding of what 5S accomplishes
