This document summarizes a group project to develop a business idea for a sandwich shop called "Sandwich Delight". It describes the original business model canvas created by the group which outlined their assumptions for key elements like value proposition, customer segments, channels, and revenue streams. It then discusses what the group learned by testing their assumptions with customer interviews and experiments. They realized customers cared more about price and taste than healthiness. Based on feedback, the group updated their business model canvas to reflect selling lower-priced sandwiches and adding delivery options.
