Want to design the next great web app? Upgrade your product, but can't decide what to add or change? Add a new feature to your product, but can't decide how to implement it? Forget focus groups. Forget endless meetings and brainstorming sessions. Throw an ultra-rapid-design party, and do it in a single day. This approach exploits the wisdom-of-crowds through a process of enforced idea diversity and voting, so no consensus, committe, or even agreement is needed. And it's way more fun.
