What are the key decision-making entities in an enterprise known as?

The term that appropriately describes the key decision-making entities in an enterprise is organizational structures. Organizational structures define how activities such as task allocation, coordination, and supervision are directed toward the achievement of organizational goals. This includes the roles, responsibilities, and relationships among various entities within the organization, such as departments, teams, and individuals.

Understanding the organizational structure is crucial because it influences how decisions are made and who is involved in the decision-making process. The clarity and functionality of these structures determine the effectiveness of communication, the flow of information, and the overall efficiency in reaching strategic objectives.

While the other options like information flows and decision structures can relate to aspects of decision-making, they do not encapsulate the complete framework of key entities engaged in making decisions within an enterprise. Management objectives, while important in guiding decisions, do not define the structure through which those decisions are made.
