There are some details you have used some senior members and above,
*Good project idea
I agree with you if you select a campaign signature based on the idea of the project.
* Quite a lot of people are interested in this project
This doesn't guarantee a well-executed project, signature campaigns with many participants but stopped and without any clarity whatsoever.
*Good team
I kind of agree, because the team was the life of the project, if the team recruited recklessly or not in the field even the project stopped
* Good bounty manager
Some people believe if bounty manager is good then the project under good, in my opinion not necessarily because bounty manager also just run the program and doesn't guarantee that the project he did it would be successful.
* Enough funds are distrubuted to the bounty hunters
This is certainly for big projects should be, but usually this is at the end of ICO, and again we cann't predict it
