By: Cecil 'Gary' Rupp

Overview of this book

Value Stream Management (VSM) opens the door to maximizing your DevOps pipeline investments by improving flows and eliminating waste. VSM and DevOps together deliver value stream improvements across enterprises for a competitive advantage in the digital world. Driving DevOps with Value Stream Management provides a comprehensive review and analysis of industry-proven VSM methods and tools to integrate, streamline, and orchestrate activities within a DevOps-oriented value stream. You'll start with an introduction to the concepts of delivering value and understand how VSM methods and tools support improved value delivery from a Lean production perspective. The book covers the complexities of implementing modern CI/CD and DevOps pipelines and then guides you through an eight-step VSM methodology with the help of a use case showing an Agile team's efforts to install a CI/CD pipeline. Free from marketing hype or vendor bias, this book presents the current VSM tool vendors and customer use cases that showcase their products' strengths. As you advance through the book, you'll learn four approaches to implementing a DevOps pipeline and get guidance on choosing the best fit.

Defining CD

CD capabilities allow product teams to stand up new environments to test new code updates with minimal manual labor and rapidly. CD's primary goal is to turn new updates into routine and high-velocity tasks that a development team can perform on-demand.

Just as CI has a sequential sequence of steps, so does the CD process, as depicted in Figure 5.5:

Figure 5.5 – CD pipeline flow

The CD pipeline view depicted in the preceding diagram provides a high-level view, and similarly to the CI pipeline, it can be decomposed into a lengthier list of related activities. These activities might include the following:

  • Conducting static code analysis
  • Conducting unit tests
  • Conducting API tests
  • Staging to test environment(s)
  • Parallel testing (for instance, useability/accessibility, exploratory, UI, and performance testing)
  • Staging to preproduction environment
  • Executing application tests (for example, acceptance, exploratory...
