ITPEC IP April 2025 Question 51
ITPEC IP April 2025 — Question 51 of 100
Use a Pareto chart — it ranks defect causes by frequency and shows their cumulative contribution.
Option (b) has descending bars for categories and a cumulative line. This makes the few causes responsible for the largest share of defects visible, helping the team prioritize corrective work where it can have the greatest effect.
Answer (b)
Why not others:
- (a) is a cause-and-effect or fishbone diagram used to organize possible causes, not rank observed counts
- (c) is a scatter diagram used to examine correlation between two numeric variables
- (d) is a flowchart used to show process sequence and decisions
Key rule: Use Pareto analysis to prioritize categories by frequency or impact; investigate their causal structure afterward with tools such as a fishbone diagram.
