Sprint: How to Solve Big Problems and Test New Ideas in Just Five Days

I have been part of design sprint at work in the past and this book for me was a refresher as well as concept builder. The book covers a unique five-day process for solving tough problems using design, prototyping, and testing ideas with customers. Design sprint is immensely useful in high stake situations when the stakes are high, when there's not enough time, or when you're just plain stuck. The book covers the design sprint over five days in detail. I found the concepts of "how we might we", "crazy eights" and "the five act customer interview" especially useful.

I have found these ideas immensely useful even without doing the complete five day design sprint.

If you are working on a high stake problem, trying to better understand customer's needs and find a product market fit, the design sprint is a great way to come up with ideas and validate hypotheses using prototypes.
