It behooves all leaders, and certainly those who are new in their role or are in a new position or organization, to inventory their performance regularly with regard to taking responsibility. 

Whether you are in charge of an organization, a department, a team or a project, one of the most important things successful leaders must do is accept responsibility. You will rely heavily on your team to get things done, to be sure, and you will need to stay open to others’ ideas, since they frequently will be better than your own. And yes, there are always unexpected bumps in the road that are totally out of your control. But if you are to be an effective leader you need to start and finish with the premise that the one thing you carry above all is ultimate responsibility.
