English to Italian Marketing Management

Due dipendenti di un'azienda stanno discutendo sulla rinegoziazione dei termini contrattuali del loro principale fornitore di carta; l'azienda intende richiedere al fornitore che esegua tutti i controlli di qualità in sede, invece che eseguirne solo una parte, prima della consegna.

Kate è alla sua prima trattativa, Carl invece ha discusso i termini originali del contratto e le sta dando dei consigli.

Ecco la conversazione:

Carl: (opening discussion) So, you want to talk about how to renegotiate with XXX so that they’re doing all the key quality checks at their site before delivery?
Kate: Right.
Carl: If they agree, we could eliminate all the checks we do. So there’s a lot at stake here.
Kate: I know. And since you worked with them on the original terms, this’ll be my first real chance to negotiate.
Carl: So far, it seems like you’ve established a good relationship with them. We’re seeing results already. It’s only been a few weeks.
Kate: I think it’s going well. Thanks. And I don't want you to think that I’m questioning the decisions we made to go this way. The ***drop-in cycle time*** alone will have a major impact on our business. XXX may look at this differently, though. Like I said, I don’t really know what to expect.

Si trovano diverse traduzioni di "cycle time" nei glossari di Proz.com, ma non colgo il senso di "drop-in" in questo contesto. Grazie mille.
