I'am currently searching my GTD processes, and your post are very interesting. Obviousy, they don't free me from working on mine.
To mpc_janssen : I hope I will see the answer from other people on your point, but, in my situation :
For me, an task can :
- be achieved after it has been initiated, and I call this kind of tasks 'action' or 'atomic tasks'.
- or it can last more (2 days, 5 days... or more), mainly because the amount of work to complete the task is long.
Knowing this, many of my task are openned in parallel and, event if it is not yet the case, I hope to be able to provide Gantt to people waiting for my tasks to be completed.
I, honestly too, don't understand why, in your situation, you don't need project to task breakdown.
How many task do you have ?
Are they just atomic tasks ?
