Each container of parts produced by a works order is individually numbered and traceable.
As soon as a full container of parts has been made on the first operation of a works order, you can move it to the next operation and start work on it.
You can send containers of parts from a works order to a sub-contractor while the previous operations are still open on your machines.
In situations where you have large works orders, you can deliver parts from a works order to your customer while the works order is still in production in your factory.
