Shu Yoshida, the Senior Vice President of Product Development at SCEA has commented that Sony employs a 'red light' process when it comes to games development in contrast to a 'green light' method. Rather than just let a project run its course, Sony would rather have the ability to give out the 'red light' should they believe that a specific project isn't going to live up to their desired standards.

So, why do we call it the “red light” process? Because any time along the way, following those meetings with people from around SCE, the game can be canceled or changed. So, rather than just “green light” a project and let it run its course, we would rather reserve the right to “red light” a project if it isn’t going to live up to our high standards. Many ideas and concepts go this route and end up canceled or put on the back burner until the market has shifted to bring it to light. When those great games end up in your living room, after years of development, there is always a development, marketing or executive team, and someone like me, eagerly awaiting those press reviews and your thoughts and comments on places like this blog.
