ITPEC IP October 2023 — Question 67 of 100
A cause-and-effect diagram resembles a fishbone and organizes factors that may cause a quality problem. The effect or problem is placed at the head, major cause categories form the main bones, and progressively detailed possible causes branch from them. It is also called an Ishikawa or fishbone diagram.
Answer (b)
Why not others:
- (a) Arrow diagram shows activity sequence and dependencies in a schedule
- (c) Pareto chart ranks categories by frequency or impact to identify priorities
- (d) Matrix diagram shows relationships between two or more sets of factors
Key rule: Use a fishbone diagram to explore possible causes; use Pareto analysis afterward to prioritize measured categories.
