QA focuses on evaluating whether processes are being followed correctly, while QC focuses on verifying that outputs meet quality standards.

Question 2

Which chart is most useful for identifying the most frequent causes of defects in a project?

Accepted Answer

Pareto chart

Answer

A Pareto chart ranks causes by frequency, highlighting the vital few issues responsible for the majority of defects.

Accepted Answer

Progress toward a specific project objective

Answer

KPIs are quantifiable metrics that indicate whether a project is on track to achieve its defined objectives and success criteria.

Question 4

What is the purpose of a control chart in quality monitoring?

Accepted Answer

To determine if a process is in statistical control by tracking variation over time

Answer

A control chart uses upper and lower control limits to distinguish normal process variation from special-cause variation requiring investigation.

Question 5

Which quality management approach emphasizes preventing defects rather than detecting them after the fact?

Accepted Answer

Prevention over inspection
