Rally team organization

Would be interesting to understand better the differences between rally team organizations in different levels. Has someone found organizational charts of WRC teams and could post an example to here? It would be nice to see the difference between WRC factory team vs. WRC2 team vs. National private R5/g.N. team. Nice comparison might be also WRC vs. F1 / Indycar team. So often in media the only visible persons are driver, co-driver, team principal and un-known mechanics working on a background.

Or anyone having knowledge to share in this?
