Scrum, the ethos of simplicity.
Anyway, the slides and a sample backlog are now available here.
It’s worth noting that for the purposes of this session I split my product backlog in to four sprints. In reality, you probably don’t know the contents of subsequent sprints until after the last sprint has been completed. Agility. Flexibility. Simplicity. It’s all about the freedom to change the order in which requirements are turned in to working value/functionality.
