Most leaders are informed about the businesses they know so that they can take informed actions.
Quite often leaders also know what they don't know so that they can monitor, observe, research etc. to inform themselves.

Most leaders are informed about the businesses they know so that they can take informed actions.
Quite often leaders also know what they don't know so that they can monitor, observe, research etc. to inform themselves.
However, leaders usually don't know what they don't know……..this is where we act.
