As the game designer you need leadership skills - you are after all responsible for the game. If you can\'t get others behind your idea, you will have difficult times.
You also need to hold the vision - as you might be the only one in the team who has complete vision for the game / product in addition to the producer and stakeholders.

You will back from one phase to previous often to iterate.
1) Idea & Concept
