Disclaimer: The reply was made in good faith that the reader might be familiar with the term 'crew resource management' and its historical contribution to flight safety. – So, sorry for the inappropriate reply.
The U.S. CFR Title 14, Part 1, Section 1.1 defines "pilot in command" as:
...the person who:
Has final authority and responsibility for the operation and safety of the flight
Edit: Mind that there is an obvious conflict between positions like, "you do as I say, because my money", and the complex relations that constitute a corporate business.
Also, "final" implies an iterative process of multiple steps, like a discussion. (Which in turn implies a certain degree of openness to such a process.) Otherwise, it would be "exclusive" or "total".
