I believe the skills necessary for an ideal properly functioning project team are: communication, good leadership, and knowledge of the problem. Everyone in this thread has already gone into great details about these skills, so I want to talk about how the team needs to be able to respect and understand each other as well. Respect isn’t a technical skill but is very important in a team. Without it the team can’t be transparent with each other and members will only try to gain something out of the project for themselves to look better and for the team. Everyone in the team could be from different backgrounds with different experiences so they all might have different opinions and ideas to bring to the table on how to tackle the project. However, if there is no respect members will not properly communication and look at the ideas proposed and the project will either never be completed or will be but could have done better if all ideas proposed were looked at equally. So yes, skills like technical knowledge and leadership are important, but understanding and respecting each member’s ideas and thoughts is just as important to a team.
