Moral and Mental Dimensions are Just as Important as the Physical

“Decisions without actions are pointless. Actions without decisions are reckless.”

John Boyd

“You gotta challenge all assumptions. If you don’t, what is doctrine on day one becomes dogma forever after.”

John Boyd


I often cite John Boyd's OODA loop when explaining how the ACD tools work, for example - ACD Cycle, Transition State Planning, The Core Story, and VIPER.

The purpose of this post is to show how John Boyd's insights and the core attributes of the OODA loop relate to specific ACD tools. The ACD tools are listed at the end of each bullet point [tool name(s)].

For those of you not familiar with the OODA loop, I highly recommend Taylor Pearson's article The Ultimate Guide to the OODA Loop.
