This document outlines the phases and benefits of a design sprint, which is a time-boxed process for teams to develop, prototype, and test ideas with end users over the course of 5 days. The phases include understanding the problem on day 1, generating solutions on day 2, voting on solutions on day 3, prototyping on day 4, and testing the prototype with users on day 5. Design sprints improve team dynamics and collaboration. They can also be scaled down to shorter timeframes. Common pitfalls to avoid include bias toward familiar or existing solutions, biased voting, issues with distributed teams or the real decision maker, and pushing predefined ideas.
