A manager is the person who is responsible for the activities of a group of employees in an organization. He has to play the role of a motivator and mentor while guiding the employees to achieve the goals of the organization. There may be supervisors under a manger to help him in his task, but the overall responsibility for the performance of the workers under him lies on the shoulders of a manger. A manager is at the lower rung of the managerial ladder that he has to climb for a prominent position in the management.
On the other hand, an executive is a person who is responsible for putting into action the plans and policies of the top management of a company. He is the person who has to see that the day to day functioning of the company carries on smoothly without any hitches. In short, an executive has to oversee the administration function of the organization. An executive has a higher standing in an organization than a manager.
