I am creating a table that lists all of the people in a group (75-125 people). I need to flag certain people with key roles in this group so they can be identified at a glance. There could be up to 10 roles that need to be flagged, and an individual could have multiple roles in a group.
My initial thought was to use a role field to display icons denoting each person's role(s), but I worry that the number of icons could become confusing and not easy to identify quickly, even with a legend.
A possible alternative is to display a field for each role in the table, but this seems like an unnecessary waste of valuable screen space.
This may be a UX 101 question, but I appreciate any guidance.
