SAFe® for DevOps Practitioners

By: Robert Wen

Overview of this book

Product development and release faces overlapping challenges due to the combined pressure of delivering high-quality products in shorter time-to-market cycles, along with maintaining proper operation and ensuring security in a complex high-tech environment. This calls for new ways of overcoming these challenges from design to development, to release, and beyond. SAFe® for DevOps Practitioners helps you use a DevOps approach with the Scaled Agile Framework and details how value streams help you resolve these challenges using examples and use cases. The book begins by explaining how the CALMR approach makes DevOps effective in resolving product development roadblocks. Next, you’ll learn to apply value stream management to establish a value stream that enables product development flow, measure its effectiveness through appropriate feedback loops, and find ways of improving it. Finally, you’ll get to grips with implementing a continuous delivery pipeline that optimizes the value stream through four phases during release on demand. This book complements the latest SAFe DevOps courses, and you’ll find it useful while studying for the SAFe DevOps Practitioner (SDP) certification. By the end of this DevOps book, you’ll have gained a clear understanding of how to achieve continuous execution and release on demand using DevOps and SAFe.

An introduction to Agile

To understand the context in which these challenges lie, it is important to understand the dominant product development process, known colloquially as Waterfall. Waterfall was used for many years to develop cathedrals and rocket ships, but when the process was used for developing software, the strains of it were beginning to show, highlighting inadequacies against the challenges of meeting a shrinking TTM and satisfying customer needs. Something had to be done.

Next, let’s look at the emergence of Agile methods from the initial attempts to incorporate Lean thinking into software development, to the creation of the Agile Manifesto and the emergence of Agile practices and frameworks.

The rise and fall of Waterfall

The method known as Waterfall had its origins in traditional product development. Workers would divide up the work into specific phases, not moving to the next phase until the current phase was completed.
