You can't keep a good idea down...
Time and technical issues may have conspired to prevent Avrom Roy-Faderman from doing his "Extreme Reusability" presentation at the OpenWorld Unconference Methodoloy Symposium, but that material has itself been repurposed and reused, and is now available on Avrom's blog.
What's Extreme Reusabilty, you ask? Avrom explains:
Development under Extreme Reusability involves developing along three separate but interacting. . .tracks: framework development, service development, and application development. These tracks are assigned to different individuals on the team, in. . .somewhere around a 20-60-20 division for a typical organization’s needs.
