I believe that picking the project team is a crucial step towards the success of a project. As people have stated above, there has to be cohesiveness from a technical and interpersonal standpoint in order for the project team to truly be able to work well together. If a technical aspect lacks then the project team might be having a great time, but might not be achieving any work. If the interpersonal aspect lacks then the project team might be getting work done, but not putting it together efficiently because of the lack of connection between team members. Additionally, I believe that even thought there might be the right balance between technical and interpersonal skills in a team, there is also the aspect of personal growth. I think that sometimes when teams get together, especially on longer projects with various phases. It is important to reevaluate team members, sometimes a new mind with a different perspective and a fresh set of eyes can really help keep the team moving forward.
