Something that I think a lot about as a design leader is how to promote the benefits of design in the organization. Paul Boag created this practical guide to guerrilla internal marketing that builds a network of ambassadors across departments and keeps user-centered thinking top of mind.

Boag, writing in his newsletter:

You cannot be everywhere at once. You cannot attend every meeting, influence every decision, or educate every colleague personally. But you can identify and equip people across different departments who care about users and give them the tools to spread UX thinking in their teams.

This is how culture change actually happens. Not through presentations from the UX team, but through conversations between colleagues who trust each other.
