D&D product manager Mike Mearls is using a software design technique (one I am very familiar with) to design D&D Next! This is really interesting if you’re a programmer. Mearls wrote:

“To start with, we work in two-week sprints aimed at producing material for the next package. If you’ve worked in software development, you might be familiar with the Scrum process. We’ve been using it since the late summer to drive our efforts, and so far it is working well. Scrum focuses our efforts on delivering features of the game—classes, races, tactical combat, multiclassing—in an iterative manner. Within that process, I serve as the product owner.” (Source)
