To go ahead and discuss about the topic sentence, we need to first see the differences in the roles of leaders and managers. According to various writers, there are some differences in between the leaders and the managers. Some say that the leaders are the innovators and the managers are the administrators (Lipman, 1996). This statement is correct as the leader tries to bring in new innovations in the organization by assigning new roles and responsibilities and the managers in turn assess the new roles and administers the team on the basis of the same. The managers tries to utilize all the resources based on the new roles and responsibilities. This statement, in some way, relates to our topic sentence that the leaders set the vision and the managers carry it out.
