Which term applies to the system of responsibilities and authority in an organization?

The term that best applies to the system of responsibilities and authority in an organization is "Organizational structure." This concept encompasses the arrangement of various roles, responsibilities, and the flow of information within the organization. It defines how tasks are allocated, coordinated, and supervised, thereby influencing the effectiveness and efficiency of the organization. A well-defined organizational structure ensures clarity in reporting relationships and delineates who is responsible for specific tasks.

While "Management hierarchy" describes the levels of management and the chain of command, it is a component of the broader organizational structure. Additionally, "Operational framework" refers more to the processes and practices used to achieve objectives rather than the overall hierarchy and roles. The "Task allocation model" focuses specifically on how tasks are distributed, rather than encompassing the full spectrum of responsibilities and authority that organizational structure indicates.
