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.

Implementing scale-free Scrum architectures

In both the original Scrum Guide and the Scrum@Scale Guide, the Scrum Team is the idealized development unit. The Scrum Team has all the skills to take a concept and run with it until it is ready for deployment. Scrum@Scale keeps the fundamentals associated with the basic Scrum Team and builds scale by simply adding new Scrum Teams as needs arise.

More importantly, Scrum@Scale implements a scale-free architecture through networked structures and scaled roles. Building on the basic Scrum Team, interconnections form in relatively small SoS Teams, ideally consisting of five people per Scrum Team and five Scrum Teams per SoS. Likewise, SoS Teams combine, as needed, to form Scrum of Scrum of Scrum (SoSoS) Teams. Situationally, the numbers can vary somewhat, but the ideal is five members for each type of team structure:
