CEO has a variety of meanings depending on the person or group using the abbreviation. The most common definition, though, is "Chief Executive Officer." In business, the CEO is the person in charge of an organization or company.
Depending on the needs of an organization, the CEO's responsibilities within it may vary. Common duties for a CEO in the business world include developing a vision for a company, communicating that vision to others and implementing it.
As leaders, CEOs evaluate the success of their businesses and direct the work of other executives. It is also the responsibility of the CEO to ensure that a business remains competitive within its industry. The CEO may be held accountable if a company fails to comply with laws and regulations or ceases to be profitable.
