I have the been scanning twitter with the #gtdsummit hashtag & it is interesting. MindManager people link to this summary, which is the on the topic I have been blogging about, but it looks best in MindManager!
Interesting how each time I see this list it is slightly different. Each new take makes more difference than it would seem. Clarify is different to process. I now call it Clarify/process/review, though as I move on I might refine that.
This map also shows the Focus area in the Making it all Work book as Responsibility.
I have a tag for AOR and AOI areas of Responsibility and Areas of Interest. I use the Focus device in Appigo To Do to show me just those Projects I want on my current list, reviewed anytime but at least weekly.
