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.

Flow Framework® and Flow Metrics®

The Flow Framework® model is described in detail in Mik Kersten’s book Project to Product: How to Survive and Thrive in the Age of Digital Disruption with the Flow Framework. In this book, Kersten describes the need to move from project-based design to product development using long-lived value streams.

To measure the performance of the value streams, Kersten proposes the Flow Framework®, a structure of Flow artifacts and the measurement of those artifacts using Flow Metrics®.

Kersten initially formulated the Flow Framework® in order to measure the flow of software delivery for his company, Tasktop. While looking at the value streams at Tasktop, Kersten identified the following four outcomes that he wanted to monitor:

  • Value
  • Cost
  • Quality
  • Happiness

He related these items to four Flow Items, which were the types of work done by Tasktop’s value streams. To track the progress of...
