I would add one more step for advisers between 5 and 6. It says a lot if project has real and known advisers who are familiar with the field and who could help the team on a way of their idea implementation. It usually decreases chances of being scammed for investors if there are at least few authoritative people who stand behind the project. Of course that's the case if not just only their photos are placed on the project's website but they really support the project.
