One of my favorite industry thought leaders to spar with is Jacob Ukelson.? His company, ActionBase, has released ActionBase 6.5, which sports a new web interface and better support for best practices.
ActionBase deserves credit for not only pursuing a different approach to "process" (some would prefer to say "knowledge work" or "ACM" - I leave it to the reader to choose the term they think fits best), but also ActionBase deserves credit for being explicit about how their products address ACM, rather than theoretical.? You don't have to imagine how it works; they make it clear through their blog, website, and demonstrations.
That being said, check out Jacob's brief presentation on the subject.
