"Oh-da," they giggled, repeating the term. "Oh-da." The Dominican human rights and nongovernmental organization workers I was instructing took delight in repeating the word, which in their Spanish-inflected pronunciation rhymed with "Yoda," rather than "Buddha," as most Americans would say it. Indeed, to the uninitiated, the term in question, "OODA," sounds strange. But regardless of its pronunciation, the acronym — short for Observe, Orient, Decide, Act — is a critical component of personal security. Consciously following the OODA Loop, the bridge that connects situational awareness and action, can keep you a step ahead of an assailant and help extricate you from a tricky situation, whatever it may be. OODA What? U.S. Air Force Col. John Boyd first developed the concept of OODA as a method to help his fellow pilots become more effective in dogfights. The system achieved its initial, narrow goal, shortening pilots' decision and action processes.
