I have several friends who retired as O6 in the Army and Air Force…and went to work for those consultancy companies.
One of them told me that they needed him to deal as a liaison between the “teams” of MBAs and the manufacturers, service providers, and the military managers. When they hired him they said that these “genius” kids could not communicate with the Gen X managers at this multi-billion dollar companies. He was there to keep everyone “happy.”
Now I did a lot of process review in my days. I would have looked at that structure and cut that job in a heartbeat. But, we never worked on government contracts. LOL
I have seen people in those consultancy systems and client corporations hired to be liaison to the liaison.
