Where to find a Dolibarr ERP business workflow document?

Both Dolibarr and ERP are new to me.
I’m trying to find a Dolibarr ERP business workflow document (or something similar), but I can’t seem to find it at https://wiki.dolibarr.org. This page only serves as a user manual for using Dolibarr.

Where can I locate or obtain commercial assistance for a higher-level document that maps ERP business workflow with Dolibarr PM modules?
