OODA Loop

Mental models

Boyd's cycle - observe, orient, decide, act - with orientation as the step where the edge actually lives, because it is where prior models meet new information. Whoever cycles faster and re-orients more honestly imposes confusion on the other side. For investors it argues for shortening the distance between new evidence and a changed position.

Robert Coram · 2002
Open LibraryGoodreads

The definitive account of John Boyd and the OODA loop. Boyd's contribution was to show that strategy is fundamentally about time and adaptation: the side that observes, orients, decides, and acts faster keeps the opponent reacting rather than acting. His ideas crossed into business, software, and lean manufacturing.
