Search by Department
Allow a search on department that displays cards for each person in that department. It would make org look-ups easier. The org structure info is already available and displayed in each users Delve page.
This is important for us. Some staff do not know who they need to speak to in a department but if they could search by department they could see the people responsible for a specific role.
Adding to this idea, when visiting a user's Delve page, make the Department field a hyperlink that generates the search for others in this department. Again, displaying all the people in the department as cards in the search results.
