This page captures relevant criteria upon which External ID providers might be assessed (actual assessment results are perhaps unlikely to fit in one table!)
Should Required vs. Desired vs. Optional answers be identified separate from assertions? Note that if so, which answers are Required, etc. will vary based on which solution approach is taken.

- "how many users using their IDs"
- etc.
- Mission: Mission of the company, including:
- Other Concerns
- EULA: Are there terms the External provider applies that are potentially in conflict with general campus policies?
