Well, here's a good example. The project is "Rewrite Document Generation System." So, we've got a project plan and a bunch of documents that evolve over time. It's a decent size project, I have to coordinate, organize, etc. the work of programmers, staff, communicate w/ users, etc.
So, I've got a project plan - which is a bunch of tasks, mostly focused on the programming orented things.
However, there's tons of "stuff" that goes with this project. Hundreds of nudges, etc. I could be doing.
So, what I think I'm supposed to do is do a full-on brainstorm/organization of the project. I've got a trigger list (see attached) and an outlining tool I like to use. So what I should do is take all the materials and notes I have, and work through my trigger list and brainstorm a super-detailed plan, then organize it as he describes. Then, on the weekly review, I'm just "picking the next task" from this super organized hierarchical plan.
Instead, what I have is a list of stakeholders and what they want, and during the weekly review I just come up with next actions. I don't have any trouble coming up with them, but (1) just looking at the name of the task and coming up with next actions isn't the same as pulling a task off an organized list and (2) I'm guessing the reason the GTD book suggests doing this is it helps identify ALL the stuff you/someone could be doing, not just what pops into your head. I'm sure that if I were able do do this process like all the other GTD people are, I'd find all sorts of tasks I could do that would make the project even better. I can start on the brainstorming thing, but about 10 minutes into it I end up not finishing it. Multiply this times 30 similarly complex projects, and there you go. I've stopped trying to brainstorm/organize during the weekly review, because I never finished a weekly review when I did that. When I make "Brainstorm/organize project X" a NA @Anywhere, that doesn't work either since I skip it because the combination of energy/time. i.e., nearly any other task on my list looks intuitively like a task that I could handle as opposed to that task. I don't think its tools, because the tool I use to outline/brainstorm is a tool I use all the time for other activities and I enjoy it. It's not that I don't know how to brainstorm, since that's how I get the team to come up with task lists, etc.
