Quote from the phoenix project book

"The First Way helps us understand how to create fast flow of work as it moves from Development into IT Operations, because that’s what’s between the business and the customer.

The Second Way shows us how to shorten and amplify feedback loops, so we can fix quality at the source and avoid rework.

And the Third Way shows us how to create a culture that simultaneously fosters experimentation, learning from failure, and understanding that repetition and practice are the prerequisites to mastery"
