Measure a workflow change rolled out to the whole org
Measure impactHardProblem. Engineering rolled out a workflow/policy change to the entire org at once (say, a new code-review policy or CI system) — no control group. Leadership asks whether it helped. How do you measure it?
Before you reveal: say your answer out loud, as if you were in the real interview — get your reasoning across clearly first. There is no single correct answer: reading what the interviewer is really after and defending your own thinking is what makes an answer strong.
