Specifically, to be counted as processed, tasks need (at least):

  • a major context, and
  • a soft date or Someday/Maybe.

It should also include (as needed):

  • 1-1 contexts or automatic delegation tracking,
  • meeting contexts,
  • action contexts,
  • task notes, and
  • a few next steps (if it is a project).

In Things, flag task as processed by dragging and dropping it to Anytime (left pane)
