Boyd’s last briefing, also called “the big crunch,” available through our “Articles” page link above.
In the 10 years after the last dated version of his major briefings, including Patterns of Conflict (available at http://dnipogo.org/john-r-boyd/), Boyd thought long and hard about the essential elements of his work. About a year before he died, this is what he came up with.
It ties together all the major elements of his work, including orientation, implicit guidance and control, Fingerspitzengefühl, the OODA loop, and the notion of “operating inside the OODA loop.” All in 3 pages.
It’s not an easy read, but it will repay many hours of deep pondering.
