ITPEC IP April 2018 Question 70
ITPEC IP April 2018 — Question 70 of 100
A cause-and-effect diagram resembles a fishbone and organizes possible causes contributing to a defined quality problem or result. Major cause categories branch from the central spine, and progressively detailed factors are added to support structured root-cause analysis.
Answer (b)
Why not others:
- an arrow diagram shows activity sequence and dependencies
- a Pareto chart ranks categories by frequency or impact
- a matrix diagram displays relationships between sets of factors
Key rule: Use a cause-and-effect, or Ishikawa, diagram to explore potential causes; use Pareto analysis to prioritize observed categories.
