Bungie Publications is an online archive of papers written by Bungie staff and delivered in games industry conferences. With sections on Art, Audio, Design, Engineering, and Production, there are *counts rapidly* 19 articles up for public view on the "Bungie Way" of making games.
Though most are written for audiences within the industry, if you're interested in "inside baseball" perspectives on the game industry they make for fascinating reading.
-- Steve's downloaded a few of these over the years, and is glad to see they're collected all in one place for easy reference.
