The two general types of processes are intermittent operations and continuous operations. Intermittent operations produce a variety of products in smaller quantities. Since a variety of products are produced, a variety of flows through the process exist. Intermittent operations tend to be labor intensive. Continuous operations produce few products in larger quantities. Resources are organized into a line flow in continuous operations. Since we are producing few products in large quantities, we can and do invest a lot of money in equipment.
