I'm looking at the idea of creating a brand(or system) persona for the application I am working on.
After reading the book 'Designing for Emotion'(and the corresponding list apart article) by Aarron Walter, I think it would be highly beneficial to have a system persona to refer to throughout the lifecycle of a project.
In his piece he talks about creating a persona for Mail Chimp and provides a really nice, but not overly detailed, template. He mentions:
Brand Traits | Personality Map | Voice | Visual Lexicon | Engagement Methods
I think, in some ways, having a tangible mascot such as Mail Chimp makes the whole process a little easier than creating one for a business app (which is closer to what I'm doing).
I am having trouble sourcing any decent articles/research on system personas - be it websites, articles, books etc.
What research is out there to show what makes an effective persona?
