Sprint: How to Solve Big Problems and Test New Ideas in Just Five Days by Jake Knapp, Braden Kowitz, John Zeratsky

2.0

Contrary to widespread praise, Knapp et al. offer yet another turnkey solution that is going work if you just do it right. In case you don't, we offer workshops. Sorry, no money-back guarantee.

Dave Snowden of the Cynefin framework calls such tactics "faux industrialisation"; an apt label for this process.

Some methods and tools might be worth your while. If you have a hipster product friend, borrow their copy and steal what you find useful.
