How do leading indicators differ from lagging indicators?
Lagging indicators report results that are already locked in — last quarter's revenue, this month's churn. Leading indicators move earlier in the causal chain and give an early read on where the lagging number is heading, which is what makes intervention possible.
Timing in the causal chain — leading indicators sit upstream (trial signups, pipeline created, onboarding completion), lagging indicators sit downstream at the outcome (revenue, churn, retention).
Certainty versus influence — lagging metrics are unambiguous but unchangeable; leading metrics are noisier and only probabilistically linked to the outcome, but they are the ones a team can still act on.
The link must be validated — a leading indicator is a hypothesis about causation, so test the historical relationship rather than assuming it, or you will optimise something that does not drive the outcome.
Pair them on the scorecard — every lagging KPI should have one or two leading drivers beneath it, so a miss can be diagnosed while there is still time to respond.
Context decides the label — the same metric can be either: customer satisfaction lags this month's service quality but leads next quarter's renewals, so classify by position relative to the outcome you care about.

Give a concrete pair from a domain you know rather than the generic "revenue vs signups" — for example, onboarding completion within seven days leading 90-day retention. The point most candidates miss, and the one that separates a strong answer, is that the leading relationship must be validated with historical data rather than assumed, since an unvalidated leading indicator is just a metric someone likes.
Mentioning that the same metric can be leading or lagging depending on the outcome shows genuine understanding. Expect the follow-up "how would you pick leading indicators for a business with none?" — the answer is to map the customer journey, instrument the steps, and test which correlate with the outcome.
