The Process Modeler is free and itself looks like a pretty good product. If you're a one-man show having to manage some project assets, or if you manage a smaller project, I can definitely see this as being useful. Process mapping is drag and drop, linking elements is a right-click away, and publishing to a website (the HTML anyway) is a simple menu button affair. Becase this is more a document and process management, and isn't really designed for timelines. It's pretty robust for a freeware app, but the catch is, for the true ISO9000 or Sarbanes-Oxley features, you'll wind up paying for a server edition.
