Final answer:
Executives are responsible for making organization-wide decisions and establishing plans and goals that affect the entire organization, often with influence over the board of directors.
Step-by-step explanation:
The individuals responsible for making organization-wide decisions and establishing plans and goals that affect the entire organization are typically executives. These top executives, such as CEOs and other C-level positions, have significant authority in shaping strategy, policies, and the overall direction of the company. They are often supported by a board of directors, who ensure that the company operates in the best interests of the shareholders, but it is the executives who usually have a considerable influence over which individuals sit on the board. While managers, supervisors, and employees also play key roles within an organization, they do not generally make decisions that affect the entire organization.
