The article discusses three Scrum scaling frameworks – Nexus, LeSS (Large-Scale Scrum), and Scrum@Scale – to aid understanding for Technical Program Managers. Nexus builds on Scrum principles with additional roles and events for multi-team coordination. LeSS takes a minimalist, holistic approach with a single product backlog and shared definition of done. Scrum@Scale extends Scrum to the entire organization, allowing for customization and introducing the concept of a Scrum of Scrums for team coordination. Choosing a framework depends on the organization’s specific needs.
