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.

DORA metrics

Since 2014, an annual report detailing the state of DevOps adoption has been published by Nicole Forsgren, Gene Kim, and Jez Humble of DORA and Alanna Brown of Puppet. Each year, they detail the general state of DevOps adoption and the maturity of respondents in adopting DevOps practices.

In 2016, they outlined certain metrics meant to measure the throughput and stability of DevOps practices across different organizations. These metrics have come to be known as DORA metrics.

The annual report has served as a barometer of the extent to which DevOps practices are being incorporated and how effectively this is being done. Each year, the report identifies the following aspects of the DevOps movement:

  • Key KPIs
  • Performance levels of organizations based on the KPIs
  • Upcoming trends

Let’s look at each of these aspects now.
