Whenever you begin a project, your brain is like a computer starting up, loading relevant information, rules, and processes into your working memory. This “boot up” takes time, and you have to redo it to a certain extent every time you pick up the project. This is why, in our design sprints, teams work on the same project for five days in a row. Information stays in people’s working memory from one day to the next, allowing them to get deeper and deeper into the challenge. As a result, we can accomplish exponentially more than we could if those same hours were spread across weeks and months.
