The Chief Executive Officer (CEO) is the highest-ranking executive within an organization who holds ultimate responsibility for the overall strategic direction, management, and performance of the company. The CEO is typically appointed or elected by the board of directors and acts as the primary decision-maker, representing the organization both internally and externally. They provide leadership, set goals and objectives, make critical business decisions, and oversee the execution of corporate strategies.

Example
In a multinational corporation, the CEO is responsible for setting the vision and mission of the company, formulating long-term strategies, and ensuring that all departments and functions work together toward achieving organizational goals. They collaborate with other executives, such as the Chief Financial Officer (CFO) and Chief Human Resources Officer (CHRO), to align resources and initiatives with the company's strategic objectives. The CEO also represents the organization in high-level meetings with stakeholders, investors, and government officials, and may engage in public relations activities to enhance the company's reputation and brand image.
