Succession Person Spotlight - Risk/Impact of Loss and Job Criticality

Summary

Succession Person Spotlight - Risk/Impact of Loss and Job Criticality

Content

I'm trying to understand where the values that would show for these three fields come from.  I assumed that Risk of Loss and Impact of Loss would come from the Profile (which could be fed by Talent Review once a meeting is submitted/completed).  I created a talent review meeting and entered values for my test cases, then submitted it, but the values are not showing when I go to their succession tab in person spotlight.

And what is job criticality?  Where/how is that defined/derived?
