The document outlines 5 keys to transforming design culture: 1) Get Inclusive - talk to the right users and not just your own assumptions; 2) Get Out - get out of the office and talk to real users; 3) Get Testing - implement more testing rather than guessing; 4) Get Journey Maps and Design Sprints - use these tools to understand user needs; 5) Get Horizontal - widen participation across departments. These keys are presented as a way to influence user-centered design and transform an organization's design culture.
