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.

Leveraging Lean Flow to Keep the Work Moving

In Chapter 1, Introducing SAFe® and DevOps, we saw the inclusion of Lean thinking approaches such as Lean software development and Kanban into the Agile movement. Jez Humble saw it as important enough to include it in the CAMS model, creating the CALMS model from which we base the SAFe® CALMR model. Scaled Agile talks about that Lean-Agile mindset with an emphasis on both Lean thinking and an Agile mindset derived from the Agile Manifesto. How does this focus on Lean thinking manifest itself in DevOps and SAFe?

In this chapter, we will see that keeping product development moving at a predictable pace requires the establishment of a Lean flow. Proper flow allows automation to succeed. To that end, we will look at the following practices to establish Lean flow:

  • Making sure all work and work progress is visible
  • Limiting our Work in Progress/Process (WIP)
  • Keeping the size of each batch of work appropriately small...
