Scaling Scrum with Nexus™
An Exoskeleton For Scaled Scrum
What is Nexus?
Nexus is based on the Scrum Framework and uses an iterative and incremental approach to scaling software and product development. Nexus augments Scrum minimally with one new role and some expanded events and artifacts. The Nexus Framework was created by Ken Schwaber, co-creator of the Scrum, and was released by Scrum.org, along with a body of knowledge, the Nexus Guide, in 2015. It preserves Scrum. As Ken describes it, “Nexus is the exoskeleton of Scrum.”
The Nexus Framework is a foundation to plan, launch, scale and manage large product and software development initiatives. Nexus is for organizations to use when multiple Scrum Teams are working on one product as it allows the teams to unify as one larger unit, a Nexus. As an “exoskeleton,” a Nexus protects and strengthens the teams by creating connections between them and by maintaining bottom-up intelligence. The foundation of a Nexus is to encourage transparency and keep scaling as uniform as possible.
Forming A Nexus
Like Scrum, it is easy to get started with Nexus, however, the Nexus Framework does first and foremost presume Scrum experience. Organizations that are already familiar with Scrum will be able to benefit from their existing Scrum knowledge. In addition to using Nexus, organizations should establish, promote, and steward technical excellence as a foundation for growth. To start a Nexus, organizations should first:
- Identify the teams in their Nexus
- Form an initial Nexus Integration Team
- Have a single Product Backlog
- Have a definition of “Done”
- Identify a Sprint cadence
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.
