Leadership vs. Management
If leadership is 'getting people to perform to their maximum potential', then I am not sure that those 'questions' are really the thing I think they are symptoms of the actions that leaders take, and the actions are bigger categories.
3 categories these would fall into are:
1) Expect positive results
2) Take care of your people
3) Put duty before self.
In order to do these things, a good leader must first declare their expectations and Show uncommon commitment.
Additionally, people will not follow you if 1) You are not an honest person and 2) you don't know your job.
The questions specifically fall into a set of actions that enable people to gain trust in you and gets them to follow you.
They can be summed into the golden rule (do unto others...)
1. Make People feel important
2. Promote your vision
3. Treat others as you would be treated
4. Take responsibility for your actions AND those of your group.
As a leader, those questions would be asked by my managers, as a leader, I put myself in their face in their daily work, so I am visible in their work life.
My managers collect data/make observations and clear the road, while I direct the car to get to destinations.
