Metrics question

How would you change the Amazon Fresh experience and how would you measure them?

What this question tests

Tests linking a proposed product change to a measurement plan for a grocery vertical with unique freshness and substitution challenges.

Identify Fresh's unique pain points versus standard Amazon shopping: item substitutions when out of stock, delivery time windows, and produce quality variance.
Propose a change: let customers pre-approve specific substitutions per item (accept similar brand, reject entirely) instead of a blanket policy.
Propose a second change: real-time delivery window narrowing (like a 30-minute arrival alert) to reduce the 'stuck at home waiting' problem.
Define measurement for substitutions: substitution acceptance rate and post-substitution return/complaint rate.
Define measurement for delivery windows: on-time delivery rate and customer satisfaction score specific to Fresh orders.

Targets substitution handling specifically, which is a well-known, real pain point in grocery delivery, showing domain awareness.
Pairs each proposed change with its own specific metric rather than one vague satisfaction score for everything.
Uses an illustrative number, e.g. assume 15% of orders currently have at least one unwanted substitution, to size the opportunity.
Distinguishes operational metrics (on-time rate) from experience metrics (satisfaction), showing both matter for a grocery vertical.

Proposing changes without pairing each one to a specific, measurable metric.
Ignoring the operational/supply-chain reality of grocery, like perishability, that makes this different from standard Amazon retail.

How would you balance giving customers more substitution control against added complexity for pickers?
How would you measure the freshness/quality problem specifically?
