It is really very hard to predict the future development of the project. Everything can change very quickly.
Often, if the team already has experience in project management, then the likelihood of success of the project increases.
A team with previously successful projects is appreciated, if not, then they try to prove themselves on the good side for future cooperation and partnerships.
In principle, I will undoubtedly deal with those people who have already done something and know about it, this is a reputation that helps with other projects and you can predict something with a higher probability.
