Looks like a point in favour of declarative vs imperative process…
A declarative system could catch this ; if say, your conditions were “must have a recent Holistic Needs Assessment report on file”, the report for the first pathway would satisfy the second without having to be repeated.
This reminds me of what’s called a “promise” in certain protocol libraries ; if your first goal declaration is processed and creates a promise that there will be a HNA report, then second goal declaration can pick this promise up and run with it, rather than having to create it’s own promise, so even if the HNA assessment hasn’t happened yet, the second goal declaration can still make use of the units the first declaration is being met with.
I’d be tempted to start with some Graphviz dot / digraph files just to illustrate the point ; we could definitely illustrate @wongwaikeong’s point that two goals could have their steps merged (in the case of Graphviz, just by merging the list of relationships). It doesn’t seem a complex thing to specify in that the core of it is “this thing needs these things”. I’d probably just go for one of the existing base dialects : YAML seems a nice fit - it looks a lot like the Debian package control file which is the basis of this notion.

Description: The GNU Parted disk partition resizing program
GNU Parted is a program that allows you to create, destroy,
resize, move and copy hard disk partitions. This is useful
for creating space for new operating systems, reorganizing
disk usage, and copying data to new hard disks.
This package contains the Parted binary and manual page.
Parted currently supports DOS, Mac, Sun, BSD, GPT and PC98
disklabels/partition tables, as well as a 'loop' (raw disk)
type which allows use on RAID/LVM. Filesystems supported are
ext2, ext3, FAT (FAT16 and FAT32) and linux-swap. Parted can
also detect HFS (Mac OS), JFS, NTFS, ReiserFS, UFS and XFS
filesystems, but cannot create/remove/resize/check these
The nature of this software means that any bugs could cause
massive data loss. While there are no known bugs at the moment,
they could exist, so please back up all important files before
running it, and do so at your own risk.
