Re: From the BBC article
"Remember, when management asks you if something can be done, they are not asking you if it can be done affordably. They think that's their decision, not yours."
Sure, but there are plenty of things that quite literally can't be done but management don't understand that.
Or the thing they want done is extremely costly and/or time consuming and you warn of this, but they assume that you're just being "unhelpful" and proceed anyway. Only to complain later that said thing has taken a long time or cost too much.
This is why it's important to have managers who understand what they're managing, not just managers who know how to managers. Managers who don't understand the field they're managing, and ignore the "unhelpful" feedback from their underlings tend to make poor decisions.
