Hello,
It is well known, that orgmode supports (but does not enforce) David
Allens GTD-approach. One aspect of this approach is to make sure, that
every project (which translates to a toplevel TODO-entry in orgmode),
has at least one subentry in state NEXT.
Now, if someone tries to advance his projects, he simply draws one of
those NEXT-entries and starts to work on it. And of course, this is
supported by orgmode, which makes it very easy to generate such a list
of NEXT-entries as part of a custom agenda.
This is how I, and probably many more people, do their daily work.
However things are not so clear, if one tries to work with priorities
too. Probably one would try to assign priorities (lets say "A" to "D")
to projects (i.e. toplevel TODO-entries); but those priorities (assigned
to TODO-entries) are not visible in the list of NEXT-entries, which is
the basis for daily work.
Inheritance would be an option, giving each NEXT-entry the priority of
its parent TODO-entry; that however would give the same priority to
*all* NEXT-entries within a given project, making it impossible to
differentiate between them. And if a project has many NEXT-entries, than
each one would have the same priority.
So (in my opinion) one needs to assign individual priorities to each
NEXT-entry, or at least to one of them. This priority assigned to the
NEXT-entry should then not be less than the priority of its project (the
toplevel TODO-entry), because if the project is important, than it
should be important too, to work on one of its pieces.
This check ("Is there any project, which has no NEXT-entries of equal
priority ?") is done by the function "org-unbacked-priorities", which
you find below and which I would like to present here for discussion.
A small example. Lets assume that you have two projects (project 1 and
2), each with some NEXT-entries (task 1 to 5):
* TODO [#A] project 1
** NEXT [#A] task 1
** NEXT [#B] task 2
* TODO [#B] project 2
** NEXT [#C] task 3
** NEXT [#D] task 4
** WAIT task 5
Now, you may see, that neither of these two projects is stuck (because
they both have NEXT-entries ready to be worked upon).
Project 2 however, has (as I would like to call it) an *unbacked
priority*. The project itself has priority "B", but none of its
NEXT-entries matches this overall priority; the highest ranking entry is
task 3 with priority of only "C".
To spot such a situation, one could use the function "org-unbacked
priorities". For the given example it would produce a list with project
2 as a single entry:
* TODO [#B] project 2
With such a list, one could then decide, either to increase the priority
of a NEXT-entry (lets say from "C" to "B") or (just the other way
around) to decrease the overall priority of project 2 from "B" down to "C".
Okay, I hope, that describes the case. Please find the named function
below. Currently it is far from perfect and has no options to be
customized (and takes no arguments either). However, if people think it
could be useful, I would be glad for any suggestions for improvements.
with kind regards, Marc-Oliver Ihm

Hi Marc-Olivier,
thanks for very clear explanations about the problem you're trying to
fix, and thanks for the code.
I'm not using the GTD-methodology myself, so I cannot really see whether
it meets a general need in the GTD world or not.
Your email and your code are good candidates for Worg, where people
share their specific problems and solutions. If you want to contribute,
please read this page :

Best,

Hello Bastien,
Yes, thats a very good suggestion ! I will post my explanation and code
on worg, which is a more fitting place for this kind of information.
Thanx !
regards, Marc-Oliver
