The Three Ways of DevOps
DevOps is more than just automating tasks; it’s about a new way of thinking. Here’s a simpler explanation of the three main principles, often called “The Three Ways“:
Think of the Big Picture
Focus on the entire system’s synergy rather than isolated components or departments. Aim to enhance the whole process, whether it involves a large division or a single individual, ensuring that every part contributes effectively to the overall function.
The flow of work is as follows:
- Work should only flow in one direction
- No known defect should be passed downstream
- Always seek to increase the flow
Improve Through Feedback
Prioritize a robust feedback loop from end-users to developers. The goal is to receive and implement feedback swiftly, enabling rapid adjustments and improvements. This approach ensures that products or services are continuously refined in response to real-world user experiences.
The Second Way describes the feedback process as the following:
- Establish an upstream feedback loop
- Shorten the feedback loop
- Amplify the feedback loop
Keep Learning and Experimenting
Foster a culture where experimentation and learning from failures are encouraged. Recognize that making mistakes and consistent practice are crucial for professional growth. This principle supports an environment of continuous improvement, where employees are motivated to explore new ideas and learn from their outcomes.
The Third Way describes the environment and culture, as the following practices:
- Promote experimentation
- Learn from success and failure
- Constant improvement
- Seek to achieve mastery through practice
