CPS Quality Control & Compliance 3

Question 1

Which quality tool is BEST suited for prioritizing the most significant sources of defects in a process?

Accepted Answer

Pareto chart

Answer

A Pareto chart ranks defect categories by frequency, allowing teams to focus on the vital few causes that account for most problems.

Question 2

A process audit differs from a product audit in that a process audit:

Accepted Answer

Examines whether processes are followed as documented

Answer

A process audit verifies that documented procedures are being followed correctly, while a product audit evaluates conformance of the output.

Question 3

Which type of control chart is most appropriate for monitoring the proportion of defective units in a large batch?

Accepted Answer

p-chart

Answer

The p-chart monitors the proportion (fraction) defective in subgroups and is used when subgroup size varies.

Question 4

What is the key difference between verification and validation in quality management?

Accepted Answer

Verification checks design requirements; validation confirms fitness for intended use

Answer

Verification confirms the product meets specified requirements, while validation confirms it meets the needs of the intended use or application.

Question 5

A supplier consistently delivers parts that are within spec but at the edge of tolerances. Which quality concept addresses the cost of this scenario?

Accepted Answer

Taguchi loss function

Answer

The Taguchi loss function shows that any deviation from the target value — even within spec — causes increasing quality loss.
