How do you create user personas that the whole org can use? (Inc. Product and Design)?

I answered this in a similar post - see it here: https://sharebird.com/can-you-outline-the-best-structure-and-format-for-user-personas-that-are-useful-across-the-org

Keep them simple. Make them as visual as possible. Define their distinctive characteristics as they relate to your product/service. Stick posters up around the building of them so that everyone "gets to know them".  Keep them on a sharable platform, so that you can have a "front page" for each and then more information about them if someone wants to know more!

Find a way to present them together on one slide, so that people can see how they are different from each other.

Does this help?

Be prepared to differentiate your personas for each internal stakeholder just the way you differentiate messaging for varying external stakeholders. You have the basics of "who" set, but you then have to think about how persona profiles inform the work of each function and approach accordingly.

For example, when working with sales, I've found it much more helpful to present the personas as business cases, rather than buyer/champion profiles. The less guessing people have to do about how to use the personas and make the information within them actionable, the better. This might require several permutations (and may not even involve calling them "personas" in some cases).
