Blue Bottle Coffee had one specific target for their sprint: helping customers choose beans. But there were several smaller pieces of the website that were involved: the home page, the list of coffees, and the shopping cart. Without a plan, every person in the sprint might sketch the same part—say, the home page—leaving Blue Bottle without enough ideas for a whole prototype. So they divided up. Each person picked a spot, then the team checked the distribution on the map (page 102).
