English to Italian Tech/Engineering Manufacturing

We are scaling to three plants which involve 3 tanks and six finishing lines. The best thing about it from my perspective is the pattern is working and the team was able to self-serve on it, follow the documentation and implement their use case without too much of our involvement.

It is actually becoming more than what I had hoped for. First, we are off the production line and right now we are doing it in-line.

si tratta di un docufilm su un'azienda che realizza lastre in vetro per schermate di TV e pc portatili che opera tramite sistemi cloud e on-premise.

non capisco molto bene il senso di "off the production line" e di in-line production...può essere che con in-line si intenda produzione propria? E l'espressione "off the production line" a cosa si riferisce?

grazie in anticipo
