Quality Assurance Manager Interview Questions
Sample answer to the question
As a Quality Assurance Manager, I use a variety of metrics to measure and track quality performance. One important metric is defect density, which measures the number of defects per unit of work, giving us insights into the overall quality of our products. Another metric is customer satisfaction, which we measure through surveys and feedback to gauge how well our products meet their needs and expectations. Additionally, I track first-time pass rate, which measures the percentage of products that pass quality tests on the first attempt. This helps us identify areas of improvement in our processes. Lastly, I monitor and track the number of customer complaints and returns, as they provide valuable insights into product quality issues. These metrics allow me to assess the effectiveness of our quality assurance processes and identify areas for improvement.
