Final answer:
Production Planning is the phase of production control that determines the amount of all resources needed for goods and services production. It involves forecasting demand and planning for meeting production goals, and sets the groundwork for scheduling, routing, and dispatching activities.
Step-by-step explanation:
The phase of production control that determines the amount of all resources needed to produce a certain amount of goods and services is known as Production Planning. Production planning is responsible for defining the requirements for materials, labor, and equipment needed to meet production goals. It involves forecasting demand, determining the capacity of production facilities, and creating a plan for the production of goods and services to ensure that the right products are made at the right time and in the right quantities.
Different aspects of production control include Scheduling, which determines when production should start and finish; Routing, which establishes the flow of materials through the production process; and Dispatching, which involves assigning specific jobs to machines or workstations. But, it is Production Planning that forms the basis of these successive stages by setting out the overall production requirements.
Therefore, when examining the options provided, A. Production Planning is the correct choice, as it sets the groundwork for all the subsequent phases of production control.
