Four risks have been plotted on a risk matrix. Which risk requires the most urgent action?

Risk W, which is high on both likelihood and impact

Risk X, because it is almost certain to occur

Risk Y, because its impact would be severe and costly

Risk Z, because it sits at the centre of the matrix

A defect rate is plotted before and after a corrective action. What should the team conclude?

The corrective action did not remove the cause and the problem has returned

The chart shows normal week to week variation with no real change

The process is still improving and needs more time to settle

The corrective action succeeded and the process is now stable at a lower level

Are the questions aligned with the ASQ CQIA Body of Knowledge?

Yes. Each question is written around topics included in the published CQIA Body of Knowledge and is tagged to the relevant BoK area. These are original practice questions and are not copied from the actual ASQ exam.

In Review Mode, you receive the correct answer and explanation immediately after answering each question. It is designed for learning, not just scoring, so you can correct misunderstandings before moving to the next question.

Does the quiz include calculations?

Yes. The free set includes a balanced mix of conceptual questions, applied scenarios and short calculations. The goal is to help you experience several common CQIA question styles.

What is included in the full CQIA practice-question package?

The complete package provides additional CQIA-style practice sets with broader Body of Knowledge coverage, detailed explanations and more opportunities to work on calculations, scenarios and commonly confused concepts.

Does purchasing the practice tests include the ASQ examination?

No. These are independent exam-preparation materials. Registration, eligibility review and the official certification examination are handled separately by ASQ.

Q1.Four risks have been plotted on a risk matrix.

Which risk requires the most urgent action?
- A.Risk W, which is high on both likelihood and impact✓ Correct answer
- B.Risk X, because it is almost certain to occur
- C.Risk Y, because its impact would be severe and costly
- D.Risk Z, because it sits at the centre of the matrix
Explanation
A risk matrix combines two dimensions, and the cell that is high on both carries the greatest expected loss. W is the only marker in the red region.

The other three need different treatments rather than no treatment. X is almost certain but minor, so it is managed by reducing how often it happens. Y is rare but severe, which calls for contingency planning rather than day to day effort. Z is moderate on both and is monitored.

Picking a risk because it is extreme on one axis alone is the error the matrix exists to prevent.

Q2.A defect rate is plotted before and after a corrective action.

What should the team conclude?
- A.The chart shows normal week to week variation with no real change
- B.The process is still improving and needs more time to settle
- C.The corrective action did not remove the cause and the problem has returned✓ Correct answer
- D.The corrective action succeeded and the process is now stable at a lower level
Explanation
The rate drops sharply after the action and then climbs back, ending in the same band it occupied before. Twenty four weeks of data show a temporary effect rather than a lasting one.

This decay pattern usually means one of two things. Either the action addressed a contributor rather than the root cause, or it was a change that depended on attention and the attention faded once the project ended.

Verifying effectiveness some weeks after implementation is what catches this. A team that checked at week sixteen would have declared success.
