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.

Measuring Value Stream Performance

In our last chapter, we started our exploration of Value Streams by referring to the Three Ways found in The Phoenix Project: A Novel about IT, DevOps, and Helping Your Business Win. The First Way was about achieving flow through the establishment of Value Streams.

This chapter moves beyond the establishment of Value Streams to verify their performance. For this chapter, we look at the Second Way: amplify feedback loops. To follow the Second Way, we need to look for and pay attention to the feedback from our Value Streams.

We can use metrics as a feedback mechanism. There are a few metrics frameworks that have emerged, such as DevOps Research and Assessment (DORA) metrics and the Flow Framework®, that can function as feedback loops.

We will cover the following topics in this chapter:

  • Creating good measurements
  • Looking at the DORA metrics
  • Looking at the Flow Framework® and Flow Metrics
  • Understanding measurements...
