The document discusses design sprints, which are a methodology for building successful products faster. Design sprints condense the traditional product development process, which usually takes 6-12 months, into a 5-day framework. This framework includes steps for problem validation, solution brainstorming, prototyping ideas, and testing solutions with customers to determine which one to take forward for development. The goal of a design sprint is to get feedback from customers earlier in the process to reduce risks and align the product or feature with customer needs from the start.
