Debriefing Today the client wrote back to me to let me know that the term is known as "debriefing" in EN. I naturally dismissed this claim because of how I understand the word debriefing, which is a short discussion/report of an event after it has passed.

I did, however, find one instance of this online to substantiate the client's claim and I thought I'd provide it here for anyone curious:
http://debrief.askdefine.com/

"In the advertising industry a debriefing has another meaning. It's the follow up on a briefing session with a client and has been described by Mark Giesbers (Talpa Digital) as: 'A debriefing is a one-page insurance policy against screwing up later on.'
Thus, the debriefing insures the agency that the questions have been interpreted correctly before they are transformed into creative answers."

I can understand why the moderators changed it - it's not really Spanish, just mangled English.

Thanks, everyone! Thanks are in order to everyone for posting your suggestions. The consensus seems to be that it's a very common term in the iberian Spanish marketing industry but is relatively unused in the US. Given the style and context of the source, I'm going with "revisions to the brief," which is essentially the gist of what many have already stated. I'm also providing "counterbrief" as an option with a strong note of caution and explanation regarding the issues surrounding it's usage.

Thanks again, everyone!

The language pair is Spanish into English To support staff/moderators: my translation is from Spanish into English, not the other way around. Please stop changing the language pairing direction. This is a very specific term in Spanish that I am unable to determine in EN and need to ask English native colleagues for help.

Thank you,
Sergio
