@Ian - good question! I think Design Personas (like other types of personas) don’t do well when they just live in a slide deck or something static like that. I’ve found that is less about documentation, and more about having reoccurring “events” or triggers that make you bring the Design Persona into the room, so to speak. I recommend having a cross-discipline team of people who serve as the Design Persona advocates throughout the company. They can spread awareness and make sure that the design persona gets inserted into the process at opportune times. They can also meet regularly and have periodic workshops to reinvigorate the design persona when needed.
