DevOps is based on three key principles: flow, feedback, and learning, which are achieved through continuous delivery, telemetry from production, and continuous improvement of the value stream.
Successful DevOps transformation requires individual change, collaborative effort, and gradual improvement of small goals to larger ones.

DevOps: Optimizing the End-to-End Value Stream
DevOps is a way of working that optimizes the end-to-end value stream through cross-functional teams that continuously deliver and improve. It is based on three key principles: flow, feedback, and learning. Flow is achieved through continuous delivery, which uses automated deployment pipelines to ensure software is always in a releasable state. Feedback is gained by using telemetry from production to monitor and improve system performance. Learning and experimentation drive continuous improvement of the value stream, where problems are solved, and new systems are designed. Successful DevOps transformation requires individual change and collaborative effort across all levels.
The Importance of Small Batches in DevOps Transformation
DevOps transformation occurs in small batches, incrementally and gradually. It involves pushing for flow, feedback, and learning across the entire value stream, with individuals at all levels working together. Transformation starts with changing individuals' thinking and goals, impacting goal setting and management practices. DevOps organizations continuously improve by addressing problems, enacting countermeasures, and designing new systems. The process of improvement is ongoing, and success is achieved by gradually laddering up small goals to larger ones. Large-scale DevOps change requires time, effort, and ongoing commitment.
