Final answer:
The policies and procedures of a food-service operation are part of control, governing the consistency and standard compliance of the processes from input to output.
Step-by-step explanation:
The policies and procedures of a food-service operation are part of control. When we examine the production process, as demonstrated in the example of pizza making, we can identify different components like inputs, which include ingredients such as flour, water, and yeast, and the efforts of the pizza maker.
The transformation involves processing these inputs through activities like dough making, sauce preparation, and baking the pizza. Finally, the output is the finished pizza, which is sold to the customer. Policies and procedures are mechanisms that help ensure these processes are consistent and meet certain standards or regulations, crucial for both internal management and external compliance, thus falling under the control aspect of the operation.
