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 the development value stream

In SAFe, discovering the development value streams gets us closer to modeling those value streams as ARTs or even Solution Trains for larger solutions.

In mapping the way solutions are developed as development value streams, we are going to concentrate on the following aspects:

  • The process and workflow
  • The people involved in the process, such as suppliers and customers

Let’s start our mapping journey by considering the process used to develop the solutions.

Finding the process and workflow

When looking at the development value stream, we can start by thinking of the development value stream initially as a black box with only its inputs and outputs visible. From there, we can piece together the intermediate steps.

The initial black box of the development Value Stream is formed by identifying the following characteristics:

  • The trigger for the development value stream
  • The first step of the development...
