OODA

Observe, orient, decide, act. It's fighter pilot terminology. If you have a faster OODA loop in a dogfight, you live. The OODA loop of your decision-making is what differentiates your ability to succeed. You want to perform slightly crazy, super-fast maneuvers, again and again.

• Observe your product, your users, and the environment, including the competition
• Orient yourself to decide what it all means
• Decide what to do
• Act
