and former Google Ventures advisers, one of the most innovative and effective books for solving tough problems in just five days. Sprint's unique methods for succes have been proven repeatedly at thousands of companies in mobile, e-commerce, healthcare, finance, and more.

Entrepreneurs and leaders face big questions every day: What's the most important place to focus your effort, and how do you start? What will your idea look like in real life? How many meetings and discussions does it take before you can be sure you have the right solution?

Now there's a surefire way to answer these important questions: the Design Sprint, created at Google by Jake Knapp. This method is like fast-forwarding into the future, so you can see how customers react before you invest all the time and expense of creating your new product, service, or campaign.

In a Design Sprint, you take a small team, clear your schedules for a week, and rapidly progress from problem, to prototype, to tested solution using the step-by-step five-day process in this book.

A practical guide to answering critical business questions, Sprint is a book for teams of any size, from small startups to Fortune 100s, from teachers to nonprofits. It can replace the old office defaults with a smarter, more respectful, and more effective way of solving problems that brings out the best contributions of everyone on the team--and helps you spend your time on work that really matters.
