The instructors wish, when they were first learning test-driving, refactoring, and OO, that they had had a side-by-side comparison between code Heaven and code Hell. Such an object lesson would have made the value and benefits of agile programming practices so much more plain, so much sooner. Alas for us, but hurray for you! In this workshop you will be able to compare and work with two very different implementations of the same problem domain: one of them fabulously ugly, and the other of them — well — a lot better. This is a close-repeat of a successful session we gave at Agile 08.
