I think that's absolutely true.
Why do you think there are "consultancy firms," like Booze-Allen, Accenture, McKinsey, etc.?
It's because most CEOs don't know what they're doing, don't know where they're going, have no vision for the future, don't understand the industry their company is operating in, and so on.
So many of them are just hoping their boards of directors, their shareholders, the family that owns them, doesn't figure out how clueless they are.
Those consultant firms exist to give the CEOs something plausible to say the next time they have to talk to the company owners.
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
Neither do Booze-Allen, Accenture, McKinsey, etc. They just fly cover for the management who should have asked their staff what to do in the first place.
