Organizational Leadership: Strategic Leadership, Project Prioritization and Selection, and Project Integration

Project Managers (PMs) are often not selected and assigned until after a project has already been selected. Why must a PM take the initiative to understand why a project that he or she has been assigned to manage was selected by an organization? What are the potential problems a PM may encounter if he or she does not understand how a project he or she is managing fits into the organization's overall strategy? Use examples to support your assertions.
