The DevOps methodology hinges on three main principles known as The Three Ways. These are:

  1. Flow: The principle of accelerating the delivery of work through the IT value stream from Development to Operations to customers.
  2. Feedback: The principle of implementing fast and constant feedback from right to left within every stage of the value stream.
  3. Continual learning and experimentation: The principle of fostering a high-trust culture in the work environment as well as a scientific approach to organizational improvement as part of the daily routine

These three principles form a cycle of continuous development, feedback, and improvement, and are what makes DevOps transformative even in different use cases.
