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.

Applying the Improvement Kata

The Improvement Kata is one of the patterns that came from the Toyota Production System and is described in detail in Mike Rother’s book Toyota Kata: Managing People for Improvement, Adaptiveness, and Superior Results. In the Improvement Kata, we follow a path toward improvement by examining the following four steps:

  1. We envision our ideal future state.
  2. We examine our present state or condition.
  3. We determine the next target that brings us closer to the ideal future state.
  4. We run an experiment, evaluating and learning in a Plan-Do-Check-Adjust (PDCA) or Lean Improvement Cycle to see if the results bring us closer to the ideal future state.

An illustration of the four steps of the Improvement Kata is as follows:

An example of teams using the Improvement Kata is an Agile retrospective. A retrospective is a meeting held at regular intervals where the team considers...
