Very similar to PointsWell. For two processes that are related, I use Process_1 and Process_2.
In this exmaple, _1 calls _2, then _2 calls _2a 2b 2e or 2f depending on IF statements in _2. I could have included all of the 2a-2f logic in _2, but making each a different process helped me keep it super clear in my mind.

As for shortcut Attribute names, I use a different naming scheme than most on the forums:
In Student BO, I have a reference Attribute called School. To shortcut various attributes of School into Student, I append _sc so I'm clear by looking at the attribute name that it is a shortcut. For example, names would be:
Student.BDL.City_sc
Student.BDL.State_sc
Student.BDL.Zip_sc
This naming convention also keeps all the attributes which are shortcuts from BDL sorted together on the Student screen in the Configuration Tool.
