What is ISA-95?
IEC 62264
An international standard that organizes how work is divided and what is exchanged between the entire company's system and the factory's system.
What it means
ISA-95 divides the company's work into several layers. At the top is the layer that handles orders, planning, and money (ERP), below that is the layer that manages manufacturing work in the factory (MES), and even lower is the layer that operates the equipment.
We also organized what needs to be exchanged between layers. It is used as a standard when discussing the boundary between ERP and MES.
At the pen factory
In a ballpoint pen factory, the work done on the office screen (order, ordering, planning) is on the upper floor, the work done on the shop floor screen (warehousing, production output, inspection, shipping) is on the lower floor, and the sensors of the assembler are on the bottom floor.
Why it matters
It serves as a standard to look at when there is conflict over which system should handle which task.
