Welcome to your interview.
The question is on your right: Tracking Development Progress and QA. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What tools and metrics do you rely on to track development progress and ensure quality assurance?
