Explanation
A Pareto chart identifies and quantifies problem sources by ranking causes in descending order of frequency or impact, visually showing which factors account for the majority of problems (the classic "80/20 rule") - making it the right tool for both identifying and quantifying root causes.
Why the others are wrong:
- A. Affinity diagram - organizes ideas into groups through brainstorming; it categorizes but does not quantify.
- B. Control chart - monitors a process over time to detect variation and trends, but doesn't identify sources of problems.
- D. Quality function deployment (QFD) - translates customer requirements into product/process design specifications; it's a planning tool, not a problem-source analysis tool.
Memory tip: Think "Pareto = Pinpoint the Problem" - the three P's remind you it's the chart that locates and measures where your biggest issues are coming from.
