The best project managers are Financial Advisors
Consider the aphorism that “communication is the tax you pay for the privilege of being in a large organization.”
The best project managers are Financial advisors. Their job to optimize your taxes: they recommend changes (to your processes) in an attempt make sure you pay enough taxes but as little as possible.
The mediocre project managers CPAs. Their job is to pay your taxes for you. They still make you do most of the work of finding paperwork and they don’t care how much you pay.
The worst project managers are auditors. They make sure you paid your taxes and bring in the authorities if you have not.
