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.

Making the work visible

Work could be defined as the effort the team or Agile Release Train (ART) (as a team of teams) may put forth to develop a product or solution. But not all that work may be focused on customer value.

The Phoenix Project: A Novel about IT, DevOps, and Helping your Business Win by Gene Kim, Kevin Behr, and George Spafford identifies four kinds of work. These are summarized as follows:

  • Business projects: Requests for new features that will bring value to the customer
  • Internal projects: Work that helps organizations continue to develop products efficiently
  • Maintenance: Work needed to maintain existing products
  • Unplanned work: Bugs, defects, and emergencies that occur from time to time

SAFe takes a few of these work categories and places them in enablers. The idea here is that enablers help create future business value. The four kinds of enablers defined by SAFe are listed here:

  • Infrastructure: This enabler exists to enhance how...
