Welcome to your interview.
The question is on your right: Measure Process Change Impact. 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.
You are a senior engineering manager reviewing a process change that moved your team from ad hoc handoffs to a weekly planning and review cadence. The team says execution feels smoother, but leadership wants proof that the change improved performance rather than just reporting. You need a way to measure the impact without confusing short-term activity with real output.
How do you measure whether a process change actually improved team performance?
