Scaling Scrum Across Modern Enterprises

By: Cecil 'Gary' Rupp

Overview of this book

Scaled Scrum and Lean-Agile practices provide essential strategies to address large and complex product development challenges not addressed in traditional Scrum. This Scrum/ Lean-Agile handbook provides a comprehensive review and analysis of industry-proven scaling strategies that enable business agility on an enterprise scale. Free of marketing hype or vendor bias, this book helps you decide which practices best fit your situation. You'll start with an introduction to Scrum as a lightweight software development framework and then explore common approaches to scaling it for more complex development scenarios. The book will then guide you through systems theory, lean development, and the application of holistic thinking to more complex software and system development activities. Throughout, you'll learn how to support multiple teams working in collaboration to develop large and complex products and explore how to manage cross-team integration, dependency, and synchronization issues. Later, you'll learn how to improve enterprise operational efficiency across value creation and value delivery activities, before discovering how to align product portfolio investments with corporate strategies. By the end of this Scrum book, you and your product teams will be able to get the most value out of Agile at scale, even in complex cyber-physical system development environments.

Each individual team within a Nexus does not produce their own product Increment. Since the Nexus is a collaborative development effort, the individual increments must be integrated and tested as a whole to ensure accomplishment of the Nexus goal.

The NIT is responsible for completing an Integrated Increment that meets the definition of "Done" within each Sprint. In that role, the NIT must help the team assess and eliminate impediments and cross-team dependencies that would complicate their work and reduce...
