Question 9 - JN0-223 discussion

The 'Three Ways' in DevOps represent key principles for achieving continuous delivery and improvement. They are:

Flow (First Way): This principle focuses on creating a fast flow of work from development to operations, reducing delays, and minimizing handoffs. It addresses technical debt by emphasizing the importance of reducing complexity, minimizing work-in-progress (WIP), and ensuring that code and infrastructure are simple and maintainable.

Feedback (Second Way): This involves creating a feedback loop that allows teams to detect and correct issues quickly.

Continuous Experimentation and Learning (Third Way): Encourages a culture of continuous experimentation, learning from failures, and innovation.

The Flow principle specifically addresses technical debt by promoting practices that prevent the accumulation of unnecessary complexity and encouraging early detection and resolution of problems, thus ensuring that the codebase and infrastructure remain maintainable and scalable.
