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 CI

Fundamentally, CI is a development approach that speeds up the velocity of software development. CI enforces a discipline that merges all developers' working copies of their code to a shared repository several times a day on a technical level. The purpose of this is to verify each incremental code integration's functionality through software build and test processes when developing the code. The goal is to ensure the main software code is always in a working and potentially deployable state.

A mature CI pipeline includes automated build and automated test capabilities; though, these two capabilities were not part of the original definition. Today, CI workflows encompass the process of taking each new code commit from the main branch (that is, the mainline code, trunk, or master) and running the appropriate steps to verify that commit.

A basic CI pipeline spans the following software development activities, as shown in Figure 5.4:
