@Jenny Leman41 Not sure I have the perfect answer (since its not a pretty RBAC chart), but I am the admin in most of our tech systems and heading out on maternity leave this winter so recently went through a similar exercise of documenting access control.

We use Ninety for process documentation (obviously :) ) and have a Core Process for "Administration". Under that, I created a Sub-Process for "Technology Admins". There I listed all the tools we use, semi-grouping them by department, but there is some overlap.

This lets anyone know who to reach out to if they feel... (More)

Following!  Been wanting to see the same thing...  thanks for asking!
