Zeratsky: Design sprints work best for products with high behavioral risk
“What we find is that the more there's a, there's kind of a big behavioral risk, the better this stuff works. So, so if you're just trying to make like a slightly better version of something that already exists, and maybe it's going to be a little cheaper or a …”
