Final answer:
Budgeting, resource allocation, and manpower are critical components at all levels of planning: strategic, tactical, and operational, to efficiently manage resources and address scarcity.
Step-by-step explanation:
The level of planning in which budgeting, resource allocation, and manpower are critical components encompasses strategic, tactical, and operational planning. In strategic planning, long-term goals and directions are established, which influence the resources and budget required to achieve these goals. Tactical planning involves mid-level planning where the resources are allocated to different departments or projects to ensure the strategies are implemented effectively.
Lastly, operational planning focuses on short-term actions, detailing the day-to-day operations and the specific allocation of manpower and resources to achieve immediate objectives. All these levels of planning require a clear understanding of resource availability and the efficient management of such resources to address the fundamental economic problem of scarcity.
