If you work on an international team, cross cultural, i have to link this in the shonons because i don't stop talking about this book. Called the culture maps by earon meyer. She discusses how different culturists communicate and collaborate effectively. And when you work with people from other cultures, they give feedback, specifically negative, constructive criticism, indifferent way. I would not do this in a group setting. Very few cultures it's ok to publicly give some one feedback, humiliate simpaty. Some cultures it's actually given.
