After a meeting, it is common to have pages of notes. Buried in those pages can be projects and next actions. So, sometime after the meeting, a sane thing to do would be to go through the notes and move the projects and next actions into your GTD system.
Question is, is the goal to remove the source material (the notes)? That is, to throw it away?
If yes, I bet there are lists of things other than projects and next actions that must be pulled out of the notes and transferred to your system.
If no, it seems as though there should be some system of links between the projects and actions you pull out, and the supporting material in the notes.
What has been your experience?
