Figure 5: Defect Pareto chart
The Pareto Chart shows the frequencies of occurrences of the
various categories of problems encountered, in order to determine
which of the existing problems occur most frequently. The
problem categories or causes are shown on the x-axis of the bar
graph and the cumulative percentage is shown on the y axis of the
graph. From the Pareto chart, it is understood that 80% of the
defect are falling under the category Logical, Requirement, Design
defect type. These defect types should be given higher priority and
must be attended first.
