In Jira Align what are the differences between selecting Scaled Agile and Hybrid settings?

[Wendy Tyler]

We are in the process of setting up Jira Align for our Enterprise.  What are the differences between the three choices in the drop down.  1) Scaled Agile, 2) Hybrid or 3) Custom.  

We are looking mainly for the differences between the first two selections.

[Tom O'Connor]

Agile Framework: Adds a specific language, estimation methods, and menus for known scaled agile frameworks. If you do not use a specific framework, select the hybrid framework.

Unfortunately I don't see anything explicitly documented in the Jira Align help that defines the key differences.  Most organizations are using Scaled Agile (SAFe) or "SAFeish" that I've always started with option 1 and made any changes from there.   I'll check to see if we have anything documented internally.

This is something I was interesting in finding out more about as well. We have someone recommending we change from SAFe to Hybrid, but I can't find anything about what changing the Agile Framework field will actually do in the environment.

Thank you!
