First, it was not clear why we discussed this topic at all, but I figured out by the middle of the seminar that the purpose might be to show us that our groups of 5 shouldn't be just groups, but instead Teams working together for one common goal. As I've understood there is no boss in a team, but I personally think, there should certainly be some kind of a leader, who puts things together, who manages the team and pushes the project further. Otherwise, there can't be an order, everyone has its own opinion and one can just not agree with others, but the work has to be done anyway. And there should be a person in charge of problem-solving within the team. I mean, that person doesn't necessarily have to command and rule, but just slightly manage team members and their activities. But that's just my opinion, will see how it turns out in our team later.
