That was some advice an executive I know shared with one of his direct reports. The executive was not being flippant, he was letting his more junior colleague know that he wanted him to come with well-thought out plans of action.
He was delegating decision making to his subordinate and wanted this individual to pick up the ball and run with it.
Such advice is the opposite of micro-management; call it “I trust you” management. It is something that every executive needs to instill in his or her people.
By permitting employees to think and do for themselves, you prepare them for greater levels of responsibility.
