Of Course It is Gray
Of course it is gray. That's why we hired you. If your job were only to make choices between black and white, we might as well use a computer program.
No, it is not clear. Your responsibility is to sense which rules are in stone and which can be ignored. It is to create and not simply follow precedent. It is to make command decisions when facts are missing and time is short; all the while knowing that a legion of second-guessers may stroll in later after a good dinner and question why you did one thing and not another.
That's why you were hired: to handle that gray stuff.
Can you do it?
