Which role researches quality problems and looks for solutions?

• A. Quality Planner
• B. Quality Investigator
• C. Quality Engineer
• D. Quality Auditor

Answer: (B)

Investigating quality problems, digging into data, identifying root causes, and driving corrective actions is what a Quality Investigator does. This role focuses on solving defects by analyzing failure modes, performing root-cause analysis, and developing solutions that prevent recurrence, often coordinating containment and corrective actions across teams to verify effectiveness.

A Quality Planner mainly defines the quality plan, requirements, and schedules to ensure processes meet standards, rather than researching and solving specific problems. A Quality Engineer concentrates on designing and improving processes to meet quality needs, with emphasis on process capability and prevention, not on investigating individual quality issues. A Quality Auditor evaluates conformity to standards through audits, identifying nonconformities, and reporting findings, but not primarily in charge of researching problems and implementing fixes.
