A company tracks customer complaints, field failures, and returned goods. These metrics primarily measure which cost of quality category?
Answer: External failure
Customer complaints, field failures, and returns occur after product delivery, making them external failure costs.
Which chart would a quality engineer use to monitor the average of a continuous variable in subgroups of size 5?
Answer: X̄-R chart
The X̄-R (Xbar-R) chart is the standard control chart for monitoring subgroup means and ranges when subgroup size is between 2 and 10.
In reliability engineering, MTBF stands for:
Answer: Mean Time Between Failures
MTBF (Mean Time Between Failures) is the average time elapsed between one failure and the next for a repairable system.
A supplier delivers a lot of 1,000 parts. Using ANSI/ASQ Z1.4 with an AQL of 1.0% at normal inspection level II, the engineer selects a sample. If the sample contains more defectives than the acceptance number, the lot is:
Answer: 100% inspected and defectives replaced
When a lot is rejected under acceptance sampling, the standard practice is 100% inspection of the lot and replacement of nonconforming items.
Which tool is used to systematically evaluate and rank alternative solutions using weighted criteria?
Answer: Decision matrix (weighted criteria matrix)
A decision matrix applies weighted scores to each alternative against defined criteria, enabling objective comparison and selection.
In a scatter diagram, a strong negative correlation between two variables means:
Answer: As one variable increases, the other decreases
A strong negative correlation (r close to −1) indicates that higher values of one variable consistently correspond to lower values of the other.
A quality management system audit that evaluates compliance against a standard such as ISO 9001 is classified as a:
Answer: System audit
A system audit examines the entire quality management system against a standard or documented requirements, rather than a single process or product.
