Question 1

A quality engineer wants to identify the vital few causes responsible for most defects. Which quality tool is most appropriate?

Accepted Answer

Pareto chart

Answer

A Pareto chart applies the 80/20 rule, displaying causes in descending frequency to help teams focus improvement efforts on the most significant defect sources.

Question 2

In software testing, what is 'regression testing' primarily designed to ensure?

Accepted Answer

Previously working functionality has not been broken by recent changes

Answer

Regression testing re-executes tests on unchanged portions of the system to confirm that modifications have not introduced new defects into existing functionality.

Question 3

Which document formally records the results of a software audit, including findings, nonconformances, and corrective actions required?

Accepted Answer

Software audit report

Answer

A software audit report formally documents what was audited, the criteria used, findings, nonconformances identified, and required corrective actions.

Question 4

What is the purpose of a 'traceability matrix' in software quality engineering?

Accepted Answer

To map requirements to test cases, ensuring all requirements are tested

Answer

A requirements traceability matrix (RTM) links each requirement to corresponding test cases, ensuring complete coverage and enabling impact analysis of requirement changes.

Question 5

Which acceptance testing approach involves having actual end-users test the software in their own environment before final release?

Accepted Answer

Beta testing

Answer

Beta testing is performed by a subset of actual end-users in their real-world environment, providing feedback on usability, functionality, and defects before general release.
