IDEO video..... belated

So I know this is late but I do need to review this IDEO video.  It was about the development process that the IDEO company goes through to develop a product.  In this video the company was redesigning a shopping cart.  I liked their process from their brainstorming to when they made the prototype.  I liked how they interviewed people to see what the problems were in addition to coming up with what they thought were it's problems.  In the brainstorming process no one shot down any ideas.  In fact, the crazy ideas ended up leading to good ideas in the future.  Also, no one person was the leader of the project.  All of them had an equal part in the project.  I feel that this system was a very effective way of going about this project.
