The four types of work–features, defects, debts, and risks–under pin the Flow Framework
The 12 factor app sets guidelines for designing software for deployment pipelines. They’re a great starting point that can be improved upon.
A look into into how fostering a culture of experimentation and learning drive continuous improvement. This is known as the Third Way of DevOps.
The Principle of Feedback, or the second way of DevOps, describes using right to left feedback in the value stream.
A look into the Principle of Flow which calls for fast feedback cycles from development to production.
