PK0-003 · Question #336

The project manager is reviewing the Pareto chart to identify if the life cycle of a deliverable is producing software bugs. Which of the following are represented in the chart? (Select TWO).

The correct answer is B. Percentage of bug types occurring C. Software bug counts. A Pareto chart displays categories in descending order of frequency, making it suitable for representing software bug counts for different bug types and the cumulative percentage of these bug types.

Why each option

A Pareto chart displays categories in descending order of frequency, making it suitable for representing software bug counts for different bug types and the cumulative percentage of these bug types.

ANumber of work units affected by the bug

While the impact of bugs might be analyzed, a standard Pareto chart focuses on the frequency of occurrences of types of issues, not the number of work units affected by each bug.

BPercentage of bug types occurringCorrect

A Pareto chart includes a line graph that shows the cumulative percentage of occurrences for each category, indicating the percentage of bug types occurring.

CSoftware bug countsCorrect

The primary bars in a Pareto chart represent the frequency or count of occurrences for different categories, in this case, the specific software bug counts for various bug types.

DRoot cause of bug occurrence

A Pareto chart helps identify which types of bugs are most frequent, but it does not directly represent the root cause; that requires further analysis after identifying the main problems.

EAffect of the bug occurrence

A Pareto chart illustrates the frequency of different bug types, not the qualitative or quantitative affect or impact of each bug occurrence.
