5. Check sheet procedure
• Classification: A trait such as a defect or failure
mode must be classified into a category.
• Location: The physical location of a trait is
indicated on a picture of a part or item being
evaluated.
• Frequency: The presence or absence of a trait or
combination of traits is indicated. Also number of
occurrences of a trait on a part can be indicated.
• Measurement Scale: A measurement scale is
divided into intervals, and measurements are
indicated by checking an appropriate interval.

6. Check sheet- Classification
• Classification: A trait such as a defect or
failure mode must be classified into a category.
Classification of defects/failure must be
technically identified
example:
Dimension
Motor speed
Wheel clearance

8. Check sheet- Location
• Location: The physical location of a trait is
indicated on a picture of a part or item being
evaluated.
Location of defects/failure must be identified
example:
Schneider manuf.Cikarang
Dripper line 2
Molding room 14 Hyundai machine ltd

10. Check sheet- Frequency
• Frequency: The presence or absence of a trait or
combination of traits is indicated. Also number of
occurrences of a trait on a part can be indicated.
Frequency of defects/failure must be identified (by a
check or stripe)
example:
√√√√√√

12. Check sheet- Scale
• Measurement Scale: A measurement scale is divided into
intervals, and measurements are indicated by checking an
appropriate interval.
Measurements scale of defects/failure must be identified
example:
Dimension : mm – failure tolerance
OUT > 100mm
High 60-100mm
Medium 30-59mm
Low 3 – 29mm

22. PARETO chart
A classification order / prioritizing order
– Pareto charts are used to identify and prioritize
problems to be solved.
– They are actually histograms aided by the 80/20 rule
adapted by Joseph Juran.
•Remember the 80/20 rule states that approximately 80% of
the problems are created by approximately 20% of the causes.
