This document discusses the design sprint process for developing solutions to problems. It describes the 5 steps as: 1) Mapping the problem by understanding it through interviews and identifying requirements and constraints, 2) Sketching solutions through creative ideation, 3) Deciding on a solution by sharing, discussing, and voting on ideas, 4) Prototyping the solution through a 3D printed object or mockup, and 5) Testing the prototype to learn about the solution through user interviews or experiments. The overall goal is to use design thinking and the design sprint approach to foster circular design through rapid prototyping and testing of ideas.
