Your question is Schedule and Quality Metrics. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What metrics do you track to ensure a project is on schedule and meeting quality standards?
Treat this as a practical project management metrics exercise. Explain how you define each metric, calculate it, distinguish leading from lagging indicators, and use it to trigger action. Assume access to a project plan, milestone tracker, issue tracker, test results, defect reports, and delivery dashboard.
