What that guy said! As much as they can suck sometimes, clear processes about how you interface with other people/teams like QA save you from a world of hurt. Sometimes it's an IT system (like a defect management system), sometimes it's an agreed way of exchanging emails, sometimes it might just be agreeing who does what.

Process is your friend, as long as the process is not so rigid that it gets in the way or clouds your creative thinking.
