The Nexus Framework
Scaled Professional Scrum · Scrum.orgWhat is Nexus?
Nexus is a framework for developing and sustaining scaled product delivery. It builds upon Scrum, extending it only where absolutely necessary to minimize and manage dependencies between 3–9 Scrum Teams working from a single Product Backlog to build an Integrated Increment.
Nexus was developed by Ken Schwaber and Scrum.org — the same people behind Scrum. It is deliberately minimal: Nexus adds exactly one new accountability (the Nexus Integration Team), a handful of extended events, and a few additional artifacts. Everything else is standard Scrum.
The core insight of Nexus is that the primary challenge of scaling Scrum is managing dependencies — dependencies in requirements, domain knowledge, and software/code. When these dependencies are minimized and managed, multiple teams can deliver a single, integrated product increment every Sprint.
Nexus preserves and enhances Scrum’s foundational bottom-up intelligence and empiricism. It does not add management layers, coordination roles, or ceremony overhead. Instead, it creates transparency around dependencies and provides accountability for integration.
