Boyd's key insight isn't that we should use OODA loops to make decisions. His genius is that OODA loops should exist, and you should set yourself up to go through the loop as quickly as possible and as many times as possible. This means designing tools or systems that can quickly go through that process. The end result is a more agile and adaptable person or organization.
I read this book years ago and it changed my life. Great understanding of the man and his life.
