In American English, the “C-suite” refers to all the various head positions at a firm, named because they all have “Chief” in their tituls. The most notorious by far is CEO, or “Chief Executive Officer”, who runs all of the other C-suite inhabitants. There are others, as CPO (privacy), COO (operating), CFO (finantial), CIO (information), and what ever other tituls the organization wants.
I am going to propose something that will add another “CCO” to the Wikipedian list already compiled: Chief Calmness Officer.
We are almost all familiar with the hair trigger of societal media going off half cocked1 on partial information, sometimes maliciously cooked up, often not.
