Planning Committee Checklist
- Has the profile been through a Connectathon in at least two regions?
- No. North America only. RAD Tech discussed and decided that this is not a barrier to FT because it was fully tested in NA and we don't expect regional variations in implementations for this profile. 10+ years have passed and we don't expect additional testing.

- Yes. NA Connectathon 2014
- Have different implementations of each actor in the profile been tested?
