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.

Mapping Your Value Streams

Value streams are an important part of the SAFe®. We saw evidence of this in Chapter 2, Culture of Shared Responsibility, when we looked at the SAFe Lean-Agile Principles and came to Principle #10: Organize Around Value. In that same way, value streams have a key role to play in DevOps. In The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win, the authors Gene Kim, George Spafford, and Kevin Behr introduced the concept of the Three Ways. The First Way is to use a value stream to establish flow and this is precisely what we will look at in this chapter.

We will examine how to discover your organization’s value stream and find future optimizations. In all, we will look at the following activities:

  • Aligning the organization’s mindset to value streams
  • Setting the context for development value streams
  • Mapping the development value stream
  • Finding areas for improvement
