I believe you need to have a good balance of someone who is knowledgeable in their role as well as a good relationship with them. Someone who you do not get along with might be more difficult to work with but someone who is more knowledgeable in their role might not see eye to eye with the rest of the group. To form a team, I believe there needs to be a few people who get along with majority of the group but some people that are knowledgeable about their role. I would avoid people who like to do things their way and won’t compromise with other people. I would choose people who know how to keep things professional and leave their personal issues at home. The team members would need to be team players and work with one another. I would avoid people who do not know how to communicate well with others. Also, someone who does not listen to the team or the manager and does their own thing would need to be avoid too.
