Large-Scale Scrum (LeSS) is a framework for scaling agile development to multiple teams. LeSS builds on top of the Scrum principles such as empiricism, cross-functional self-managing teams and provides a framework for applying that at scale. On top of them, LeSS provides simple structural rules and guidelines on how to adopt Scrum in large product development.
The Certified LeSS Basics course is a brief introduction to the LeSS Framework. It provides an 8 hour overview of the framework and some of the essential concepts that it uses.
The participants have passed Scrum foundations courses taught by an accredited trainer, e.g. Applying Professional Scrum™ (Scrum.org) or have acquired the same knowledge from reading and practising. Participants' knowledge level can be evaluated using pre-course evaluation for Scrum (https://less.works/less/assessment/scrum).
