Question

I have a question about the following sentence. 
“These components are produced off non-production process.” What does the “off” means in the sentence? How can I rephrase it?

Answer

In the sentence, "off" is used in an incorrect way. It should be "of" instead. The correct sentence should be: "These components are produced off a non-production process."

To rephrase the sentence: "These components are manufactured using a non-production process."
