Which software quality practice helps ensure product quality by measuring performance against targets?

• A. Track defects against quality targets
• B. Use metrics to manage
• C. Use system based software design
• D. Idle workers

Answer: (A)

Measuring performance against targets means setting clear quality goals and continuously checking actual results against them. Tracking defects against quality targets does exactly that: you have predefined acceptable levels of defects, and you compare the number and severity of defects observed during testing or in production to those targets. If the measurements exceed the targets, you trigger investigations and corrective actions to bring quality back within bounds, driving continuous improvement. Using metrics to manage is related, but broader; it emphasizes collecting and using various metrics to guide decisions, not necessarily tying them to specific targets. System-based software design focuses on architecture and design methods rather than measurement against targets. Idle workers doesn’t contribute to quality measurement at all. So, tracking defects against quality targets is the practice that most directly ensures product quality by measuring performance against targets.
