The Task Analysis Grid is an interesting alternative to the standard requirements doc. I think I may give it a whirl at my next opportunity. As noted on the site, it’s a “single document allows anyone looking at it to see the entire scope of a project, figure out what’s in this release (1) as well as what we’re planning for future releases (2, 3, and 4). It’s an extremely effective artifact for getting everyone on the same page.” The numbers (1 – 4) map to priority levels assigned to each requirement.
