3. Classic Quality Tool 1: Flowchart
Maps the sequence of steps and decision points in a process
Helps group to have common understanding of the process

4. Classic Quality Tool 2: Check Sheet
Also known as a tally sheet
Helps gather data on the frequency of occurrence of particular events or defects
Check sheet design often requires prior knowledge of the process

5. Classic Quality Tool 3: Cause-and-Effect Diagram
Other names
Fishbone diagram
Ishikawa diagram
C-E diagram
Used to show the many different causes that may contribute to a problem (effect)
Causes are frequently generated through brainstorming sessions

7. Classic Quality Tool 4: Pareto Chart
Pareto (an 1800s Italian economist) noted that 80 percent of the wealth in Italy was held by 20 percent of the population
Juran (20th century) 80% of the variation in a process is caused by 20% of the variables
20% - vital few
80% - trivial many or useful many

8. Classic Quality Tool 4: Pareto Chart
Causes are frequently documented in a check list which is used to generate a Pareto chart
Managers use Pareto charts to help focus or prioritize process improvement efforts

9. Classic Quality Tool 5: Control Chart
Purpose
Indicates how a process behaves over time
Shows when a process is being influenced by special causes
Chart consists of UCL, CL, LCL, and data points
Examined for nonrandom patterns

10. Classic Quality Tool 6: Histogram
Bar graph that represents the frequency distribution of the data
X-axis shows cell boundaries
Y-axis shows cell frequency
Shape of the bars is only a rough indication of the distribution

11. Classic Quality Tool 7: Scatter Diagram
Also known as an X-Y graph
“Shows whether or not there is a correlation between two variables”
Caution: A statistical correlation does not guarantee a direct cause and effect
Linear/nonlinear
Positive/negative
