In my opinion, it is one of those words in Italian that do not mean much but convey a brilliant idea that should catch up the consumer's attention. Starting from Irene's proposal, I've worked out my own solution that is -like it or not- "technical performances". Thanks a lot for sharing this translation experience with me ! M."
