Systems and practices.

Systems and practices Production systems consist of inputs,

processes, outputs and feedback. There are different scales of food production that require different kinds of equipment. CAD and CAM can be used to design, test, and monitor processes. Standard components can be used to speed up production. Safety is ensured through hazard analysis and critical control point checks.
