When it comes to building a project team it is definitely necessary to focus on skills and not personal relationship. I do not believe that it is healthy from work and personal life to overlap too much so to avoid better friends with you and your team or amongst team members should be avoided. I think that obviously personal relationship does have a small role in that people need to be able to work together. Members that fight or overshadow each other can be detrimental to the team’s ability to complete a project. I think that too many people that are considered the best at their job could cause an ego issue. I also believe that it is important to have many different skill sets. Even if a project seems like a mechanical engineering project you should still have a business major to deal with marketing and electrical engineering to help with motor control and so on and so forth.
