Exploring familiarity can be done in multiple contexts depending on which question you are looking to answer.
If you want to know who is familiar with a given piece of information (and how familiar they are), navigate to that piece of information and open the Familiarity panel.
If you want to know the level of familiarity of pieces of information relative to their siebling, select the "Familiarity" view type in the view type dropdown.
This will display the awareness and familiarity of each individual item, sorted in ascending order first by awareness, and then by familiarity.
The familiarity view type is supported when viewing:
If you want to know how familiar all role holders are with a given role, navigate to that role, scroll down to the "Role holders" section and examine the progress bars located there.
