regarding "working backward" and my comments about Henry Gantt's (and
others') views about working backward from the desired result or end state
instead of forward from current conditions:

No, I didn't. Would you mind citing it for me so I can check it out?
And, just to be precise, I didn't name a single source, I cited a couple
of them as illustrative of earlier views on the same general concept.
The earliest documented source of the idea of "working" (and "thinking")
backward of which I am aware is the Greek mathematician Pappus (c. 300
AD). Polya, a noted mathematician in his own right, and author of "How to
Solve It" (1945), quotes Pappus as follows:
"Inquire from what antecedent the desired result could be achieved."
