If you are participating in a brainstorming session for your company and you come up with a fantastic idea, then you should share it. This is not time to hold back, and your great idea, shared in a group that is open to expansion of an idea, could turn your fantastic idea in to the perfect idea. This and other brainstorming techniques are the reason that brainstorming is so effective. Having a group of people roll around with an idea and share their thought processes with others is often the reason that many companies find the perfect product or marketing ploy.
