Day 1: Understand
Day 2: Sketch
Day 3: Storyboard
Day 4: Prototype
Day 5: Test

They also published a series of Medium posts outlining a typical sprint week, not to be confused with a typical Shark Week.
If you need a manageable framework for iterating quickly, get the book on Amazon Sprint: How to Solve Big Problems and Test New Ideas in Just Five Days and give it a shot.
