Single-System or Multiple-System Automation

You can also choose between single-system and multiple-system automation. When beginning new automation, start with single-system automation. That is, automate as many operations locally (at each system) as possible before moving to multiple-system automation. You thereby reduce the number of interactions needed with other systems to achieve full multiple-system automation. You also avoid overtaxing the communication facilities, focal-point systems, and telecommunication lines.
