Scaling Scrum with Nexus
A Framework to Help Organizations Scale Scrum
Why Scale Scrum with Nexus?
Scrum is a simple framework for delivering products using an empirical approach in which teams deliver value in small increments, inspect the results, and adapt their approach as needed based on feedback. It consists of a small set of events, accountabilities, and artifacts, bound together by practices, and enlivened by values that are the key to making it work.
Nexus builds upon Scrum’s foundation, and its parts will be familiar to those who have used Scrum. It minimally extends the Scrum framework only where absolutely necessary to enable multiple teams to work from a single Product Backlog to build an Integrated Increment that meets a goal.
A Nexus is a group of approximately three to nine Scrum Teams that work together to deliver a single product; it is a connection between people and things. Nexus seeks to preserve and enhance Scrum’s foundational bottom-up intelligence and empiricism while enabling a group of Scrum Teams to deliver more value than can be achieved by a single team. It does this by helping these teams to reduce the complexity created by cross-team dependencies that they encounter as they collaborate to deliver an integrated, valuable, useful product Increment at least once every Sprint.
Nexus is based on the Scrum framework and augments Scrum minimally. The Nexus framework was created by Ken Schwaber, co-creator of Scrum, and was released by Scrum.org, along with a body of knowledge, the Nexus Guide, in 2015 and updated in 2018 as well as 2021. The changes made in the 2021 version are discussed in the below episode of the Scrum.org Community Podcast.
The Nexus Framework for Scaling Scrum
The Nexus Framework for Scaling Scrum is a concise book that shows how Nexus helps teams to deliver a complex, multi-platform product in short, frequent cycles, without sacrificing consistency or quality, and without adding unnecessary complexity or straying from Scrum’s core principles. Using an extended case study, the authors illustrate how Nexus helps teams solve common scaling challenges like reducing cross-team dependencies, preserving team self-management and transparency, and ensuring accountability.
As with Scrum, Nexus alone isn’t enough for success, but it helps drive to the heart of the scaling issue – continually identifying and removing dependencies created by increased complexity. You will also need several techniques to bind the work of the Scrum Teams in your Nexus and that is why we have developed and reformulated over 50 practices to help you launch and sustain a Nexus predictably. Find a list of suggested practices here.
