Driving DevOps with Value Stream Management

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. By the end of this VSM book, you'll be ready to develop and execute a plan to streamline your software delivery pipelines and improve your organization's value stream delivery.

Improving IT flows through Lean Thinking

In the next chapter, you will learn how to apply Systems Thinking to reduce complexity across six potential value streams involving one to six sets of activities (See Figure 3.2, an image showing nodes, potential connections, actual connections, and network densities.) The graphic provided demonstrates how aligning value stream activities as streamlined flows reduces the number of possible connections and interactions across the activities. Thus, the linear-sequential approach is the most efficient way to operate within a value stream.

However, we can still mess things up by not reducing the setup and cycle times of lengthier activities and allowing work items to queue at those slower activities within the value stream. As noted previously, the ideal goal is to match each activity and the overall production rates to the rate of receiving customer orders or requirements. We can calculate this as the time to produce work items, divided by the...
