Who are the business decisions of a corporation made by?

Business decisions in a corporation are typically made by a combination of the board of directors, executive leadership (such as the CEO and other top executives), and various management teams. The board of directors sets the overall strategic direction and governance, while executives implement strategies and make day-to-day operational decisions. Additionally, input from employees, shareholders, and stakeholders can influence decision-making processes. Ultimately, the collective expertise and perspectives of these groups shape the corporation's direction and performance.
