Found the following blurb from the Heritage Institute to be particularly poignant:
A quality of leadership is the assumption and acceptance of responsibility for the organization and all decisions taken within the organization.
The leader is also responsible for making strategic decisions within the leader's responsibility rather than avoiding or abrogating this responsibility.
A culture of taking responsibility cannot exist in a culture of blame and recrimination. A leader in a culture of responsibility, takes responsibility and shares the credit.
Where have you gone, Harry Truman?
