Design sprint
Design sprints were originally developed by Jake Knapp.[1] They can help designers quickly come up with ideas and solve problems.
Usually, a design sprint includes 5 stages, with each one lasting a single day. The stages include mapping, sketching, deciding, prototyping, and testing. The idea is that when you work this fast, you fail faster and learn more quickly. Ideas are tested promptly so that a perfect solution is found faster.
