An entrepreneur is a person who creates something new and assumes the risks and rewards associated with that innovation. S/He gets profit as his reward for bearing risks. A manager is a person responsible for controlling or administering an organization or group of staff. S/He does not bear any risk involved in the enterprise. Entrepreneurship is one of the most important inputs in the economic development of a country.
I think it is true that at times an entrepreneur can be a manager also but a manager cannot be an entrepreneur. There are some important reasons behind my thought which is presented below:
(a) The main motive of an entrepreneur is to start a venture by setting up an enterprise but the manager always wants to render his services in an enterprise already set up by someone else. Here an entrepreneur is able to render his services in an enterprise but a manager does not think to build up an enterprise.
(b) An entrepreneur is an owner but a manager is a servant in the enterprise. In this case, an entrepreneur may be the servant but a manager may not be an owner.
(c) A manager as a servant may or may not bear any risk involved in the enterprise. But an entrepreneur bears all risk of an enterprise.
(d) An entrepreneur himself thinks over what and how to produce goods to meet the changing demands of customers as well as executes his own plan. But a manager only executes the plans prepared by the entrepreneur.
(e) An entrepreneur is the final decision maker but a manager may or may not be a decision maker because an entrepreneur has the right to avoid the decision of a manager.
Finally, we can say that an entrepreneur may have the opportunity to be a manager but there is no option of a manager to be an entrepreneur.
