I believe in my opinion, the best way to form a project team would be with people who are more knowledgeable in their department role rather than working with people who you have a better relationship with. The reason being, with people being expertise in a certain field will help you perform a specific task from your group member. This will help you form a project team where each member can contribute something valuable to the project. As long as you are able to manage, along with the team members, the project and not procrastinating then you are on the right path of performing your task. Despite not having a better relationship with your team members you know that everyone has a responsibility and they have to work up to it. Whereas, when you are working with people who you have better relationship with, you are bound to rely upon each other to do the work. Working with different people can also help you learn something new from them. Thus, I believe that working with different minds in their own expertise would be a better option to form a project team.
