Food Delivery App Design Covering Seller Tools, Ordering Flow, Nearby Search, MVP and KPIs

Design a food delivery app. Cover how a customer moves through the app to place an order, how the app finds hotels near the customer's location, the app that sellers use to run their side, what the minimum viable first version includes, and how you would measure success. ### Clarifying Questions - Is this a new standalone app competing with established delivery apps, or a delivery feature inside an existing product? - Does "food" mean ready-to-eat meals only, or also groceries and convenience items? - Who delivers the orders: couriers we recruit, the sellers' own staff, or a third-party delivery partner? ### Part 1 — Customer ordering flow Lay out the customer's journey from opening the app to receiving the food, and describe the main screens and decisions along the way. ```hint Follow one order Walk a single order from the first screen to the doorstep, and mark each point where a customer might hesitate, lose trust or give up. ``` #### What This Part Should Cover - Each step of the journey and the main screen or decision at that step - Where customers drop off or lose trust, and how the design reduces it - What the customer sees when an order goes wrong ### Part 2 — Location-based hotel search Explain how the app works out where the customer is, which hotels it shows them and in what order. ```hint Two questions, not one Separate "which places can serve this address right now" from "which of those should appear first". ``` #### Clarifying Questions for this Part - By "hotel", do we mean restaurants and eateries, or places to stay? #### What This Part Should Cover - How the customer's location is captured and corrected - How serviceable places are determined, ranked and filtered - What the customer sees when few or no places can serve them ### Part 3 — Seller app UX Design the app that restaurants and other food sellers use to manage their business on the platform. ```hint Design for the rush Picture the device on a counter in a busy kitchen at peak dinner time, and design for that moment before the quieter screens. ``` #### What This Part Should Cover - Onboarding and menu setup - Receiving orders and keeping availability accurate during busy periods - Payouts, performance feedback and support ### Part 4 — Minimum viable product Define the first version you would launch and what you would leave out. ```hint Smallest real loop Ask what the smallest launch is that still lets a real order be placed, prepared, delivered and paid for. ``` #### What This Part Should Cover - The launch scope (where, which sellers, which features) and the reasoning behind it - What is cut or handled manually at first, and what would trigger building it - Which risky assumption the launch is designed to test ### Part 5 — Success metrics Choose how you would measure whether the app is succeeding. ```hint Count every side Check that your metrics can see sellers and deliveries as well as customers. ``` #### What This Part Should Cover - A north-star metric and why it reflects value for both customers and sellers - Supporting metrics for each side of the marketplace and for delivery - Guardrails that catch growth bought at the expense of quality, sellers or unit economics ### What a Strong Answer Covers - A stated goal and a chosen set of target customers and sellers that all five parts serve consistently - How the plan gets enough sellers and customers at the same time for the marketplace to work at launch - Prioritization and trade-offs explained across the parts, not just feature lists - Risks to the plan and how each is mitigated ### Follow-up Questions - Sellers complain that the commission is too high and threaten to leave. How do you respond? - Late deliveries spike on rainy evenings. What would you change in the product and in operations? - After launch, how would you decide between expanding to a second city and deepening the first?
