Hmmm....One of the things that I like about OmniFocus is that it DOES allow me to thinkl about what "done" looks like.

I put a project in my inbox as a placeholder and I leave it there until I figure out what done looks like. When successful, I have a project with multiple steps defined all leading up to what make that project complete.

In some cases, when something is fairly complex or "done" depends on too many unknowns, I put as the final step "fill out steps to completion in OmniFocus" with some date certain as a start date.

Between these two methods, I have kept a pretty good handle on "done."

With respect to the rest of your comment, I think OmniPlan is what you need. version 2 of OmniFocus is suppposed to have integration with OmniPlan, so you will have to wait for awhile before you are a happy camper.
