CompTIA Project+ (PK0-005) — Question 2

During a quality analysis review, the causes of several issues have been highlighted. Which of the following should the project manager use to identify the MOST important causes?

Answer options

• A. Ishikawa diagram
• B. Scatter diagram
• C. Pareto chart
• D. Decision tree

Correct answer: C

Explanation

The Pareto chart is specifically designed to highlight the most critical issues by illustrating the frequency of problems, allowing the project manager to focus on the most significant causes. The Ishikawa diagram helps in identifying potential causes but does not prioritize them. The scatter diagram is used to show relationships between variables, while the decision tree assists in decision-making processes rather than identifying primary causes.
