OODA Loop

John Boyd's decision cycle: Observe → Orient → Decide → Act. The key insight isn't the steps themselves but the speed of cycling: whoever can run through the loop faster gains a decisive advantage by acting on more current information while the opponent is still processing outdated information. Orientation—the most critical step—means making sense of observations through your mental models, culture, and prior experience.

When to use it

In competitive situations where speed matters. When designing decision-making processes. When an organization is slow to respond to market changes. When building strategic agility.

How it can help

The primary framework for competitive speed and agile strategy. Helps leaders design organizations that sense, interpret, and respond faster than competitors. Explains why agile startups beat slow incumbents: faster OODA loops, not more resources.
