That is the wrong view. Innovation comes in many different packages, but one thing is certain it requires discipline and hard work. It is not real easy for most of us to flip a switch and suddenly become a creative genius. Yet isn't it interesting how often we approach it that way. Go into the same old boring conference room, with the same old cluttered flipchart or dirty whiteboard, and the same old boring black markers and the same table and chairs lined up in the same old boring corporate formation , and somehow get unbelievably stimulated to come up with a wide variety of creative options.
Innovation requires stimulus.
You must be able to think about things in new and unusual ways or see things from entirely different perspectives. Lay all the pictures out on a table and talk about the factors that made them appealing. List those factors on an easel. Subdivide your team and ask a subgroup to go to each easel paper. Have them discuss and list one idea about the problem you are addressing, that relates to their factor.
