One factor that contributes to this is the often competing goals of Development and IT Operations. IT organizations are responsible for many things. Among them are the two following goals, which must be pursued simultaneously:
- Respond to the rapidly changing competitive landscape
- Provide stable, reliable, and secure service to the customer
Frequently, Development will take responsibility for responding to changes in the market, deploying features and changes into production as quickly as possible. IT Operations will take responsibility for providing customers with IT service that is stable, reliable, and secure, making it difficult or even impossible for anyone to introduce production changes that could jeopardize production. Configured this way, Development and IT Operations have diametrically opposed goals and incentives.
Dr. Eliyahu M. Goldratt, one of the founders of the manufacturing management movement, called these types of configuration “the core, chronic conflict”—when organizational measurements and incentives across different silos prevent the achievement of global, organizational goals.
THE PRINCIPLES UNDERPINNING DEVOPS
The Phoenix Project presents the Three Ways as the set of underpinning principles from which all the observed DevOps behaviors and patterns are derived.
The First Way enables fast left-to-right flow of work from Development to Operations to the customer. In order to maximize flow, we need to make work visible, reduce our batch sizes and intervals of work, build in quality by preventing defects from being passed to downstream work centers, and constantly optimize for the global goals.
The Second Way enables the fast and constant flow of feedback from right to left at all stages of our value stream. It requires that we amplify feedback to prevent problems from happening again, or enable faster detection and recovery. By doing this, we create quality at the source and generate or embed knowledge where it is needed—this allows us to create ever-safer systems of work where problems are found and fixed long before a catastrophic failure occurs.
The Third Way enables the creation of a generative, high-trust culture that supports a dynamic, disciplined, and scientific approach to experimentation and risk-taking, facilitating the creation of organizational learning, both from our successes and failures. Furthermore, by continually shortening and amplifying our feedback loops, we create ever-safer systems of work and are better able to take risks and perform experiments that help us learn faster than our competition and win in the marketplace.
