The question is how to determine that a project will be successful. This is almost impossible to do.
I cannot know in advance that the project will be successful, but the information and experience of the team will give confidence in the possibility of implementation, I will see the team's approach to work and this will interest me.
I think it is not necessary to hurry and see the project in development, to see the realization of the planed ideas. What the team has realy done.
