ITPEC FE Morning October 2019 Question 55
ITPEC FE Morning October 2019 — Question 55 of 80
Pareto Diagram — bar chart sorted by frequency + cumulative line graph overlay.
A Pareto diagram arranges categories (e.g., cost, schedule, quality issues) as bars in descending order of frequency, with a cumulative percentage line superimposed. It helps identify the "vital few" causes that account for most problems (80/20 rule).
Why not others:
- (a) Cause and effect diagram (Ishikawa/fishbone) shows root causes of a single problem, not frequency ranking
- (b) Control chart tracks process values over time against upper/lower control limits (UCL/LCL)
- (d) Scatter diagram plots two variables as dots to show correlation
Key rule: Bars sorted by descending frequency + cumulative line = Pareto diagram.
