I just found the law.com's e-discovery roadmap which is based on the edrm project. Indeed, the law.com's e-discovery site in general looks decent and was immediately added to my blogroll.
I love FRCP 34b. No insightful comments; the roadmap is simply the most indepth process cycle i've seen yet and is worth it's weight in gold considering how new the entire thing is.
Unless you want to rely on your vendor to define your processes.
