Food Truck Software: Customer Ordering App, Crew Tools and Server Architecture

Design the software for a food truck business, covering both the front end that its users interact with and the back end that runs behind it. ```hint Start from what moves List the ways a food truck differs from a restaurant with a fixed address and a steady internet connection, and let each difference earn its place in the design. ``` ### Clarifying Questions - Is this for one owner running one or a few trucks, or a platform that many trucks and their customers share? - Which users should the first version serve: customers finding the truck and ordering ahead, the crew taking and cooking orders, or the owner managing the menu and schedule? - Should customers order and pay in the app, or does the system only need to show where the truck is and what is on the menu while payment stays at the window? - Can we count on the truck having a cellular data connection during service, and what should happen when it drops? ### What a Strong Answer Covers - Scoping: which users the system serves and the few core journeys the first version must support - The front-end surfaces for customers, crew and owner, and what each one has to do - Back-end components, data model and APIs for location and schedule, menu and inventory, orders, payments and notifications - Constraints specific to a mobile vendor (changing location, lunch-rush spikes, sell-outs, unreliable connectivity) and the failure handling each needs - Build-versus-buy decisions, an MVP-to-later roadmap, and how success would be measured ### Follow-up Questions - How would the design change if this became a marketplace serving hundreds of trucks across a city? - What happens to an order that has already been paid for when the truck loses connectivity or sells out of an item? - Which parts would you buy off the shelf rather than build, and why?
