Anatomy of a Brainstorm Session

We've been slacking off on our Product Design and Development assignments. It was time for a a team meeting to decide on a concept (as a reminder, we're doing a produce plastic bag dispenser). We picked an empty classroom in building 1 (inadvertently kicking out a class that was to start an hour later in that same room) and held an intense brainstorm. Rules of the game: 1) anything goes, and 2) don't judge the ideas (we'll do that later). We started with the "classic" ideas we had in our minds all along. Ziv presented his printer roller idea to an approving look from Regan:
Then it was Shelley's turn to present her ideas (drawing a skeptical look from Ziv):
As we went on, something interesting happened. We started to think "outside the box". What if we don't even need a bag? What if we can just drop the item in a black box that wraps it up nicely, labels it and prints the price? Hmmm... The brainstorm was starting to kick-in some good ideas. Every piece of blackboard in that room was covered. We began to shout out crazy thoughts. Tempers flared! It became so intense that Ziv almost strangled Regan! In turn, I almost choked Ziv with the object of our attention: the puny plastic bag.
Of course, we were just having fun. The brainstorm session was a great succcess. We have some "safe" concepts, but we also have some far-out ones that need to be explored further.
