Growth-driven design asks a team to research its audience before designing, launch a focused first site, improve that site in short measured cycles, and share what it learns with the rest of the company. The method's own pages tell you what those principles are. Usability research from before the method existed supports the reasoning behind iteration. Agency case studies report what happened on particular sites, and the one discussed here is a before-and-after account without a control group.
