What this question tests

Product design for a B2B hardware and software product serving both restaurant operators and diners.

Define both users: diners wanting a quick, easy way to order and pay, and restaurant owners wanting higher table turnover and lower labor cost.
List pain points: slow wait times for a server to take orders or bring the check, and restaurants needing more staff during peak hours.
Prioritize core features: menu browsing, ordering, and pay-at-table, since these directly reduce wait and turnover time.
Design for restaurant operators: an easy way to update menus and prices without needing engineering support.
Address monetization: charge restaurants a subscription or per-transaction fee, since diners shouldn't be charged directly.
Define success as table turnover time reduction and restaurant retention after a trial period.

Designs for both sides explicitly, diner convenience and restaurant operational efficiency, rather than only one.
Names a concrete operational benefit, faster table turnover, which restaurants care about more than diner delight alone.
Proposes a self-serve menu management tool for restaurant owners, addressing a real operational pain point.
Picks a business-relevant metric, restaurant retention, alongside a diner-facing metric like order completion time.

Designing only for the diner experience and ignoring restaurant operator needs and incentives.
Ignoring monetization and who actually pays for the tablet and software.

How would you price this for restaurants of different sizes?
How would you handle restaurants that don't want to change their existing workflow?
