In the book Extreme Programming Installed, Ron Jeffries et al. (Addison-Wesley Longman Publishing) describe the story process best: Card Write what you’d like to see in the software on a bunch of index cards. Conversation Get together and have a rich conversation about what software to build. Confirmation Together agree on how you’ll confirm that the software is done. If it sounds simple, it’s because it is. Just remember, simple isn’t easy.
