what is the importance of collaborative work of sophisticated people on an important task?
Why is it important that people collaborate to perform an important task ? Some tasks cannot be performed by one person alone. The design, for example, of a major engineering work (a tunnel under the sea, perhaps). The construction of a skyscraper. The production of a new opera. Some tasks need collaboration and, (I'm going to guess that you have translated 'sophisticated'), they need collaboration by intelligent, brilliant people.
I hope that I have understood your question and that this helps a little.
