Initial processing: actionable, but not next
I'm implementing GTD for the first time. I wanted to share an observation: As I go through my inbox ("Getting 'in' to empty"), I find a lot of stuff that's actionable, but it's not really the next action; it's more like step 12 of 30. At first, I didn't know what to do with those things. I'm guessing that the value of the next action list is precisely that every thing on there can be done next--that is, it's not dependent on doing something else first.
So where to put those things, I wondered. I realized that these things were really more like project support material.
I'd be interested to hear whether/how others dealt with this in their initial processing of their inbox.
RE: Initial processing: actionable, but not next
Every project can have a list of actions which are not (yet) next actions. How long the list is depends on the complexity of the project and how much project planning has been done. The tasks you describe seem to belong in these lists, below other actions on which they depend. In Outlook, this list is part of the Notes field for the project.
Hope this helps!
