Guide to Large Scale Scrum (LeSS)

Large Scale Scrum (LeSS) is a lightweight, flexible, framework that has been designed to tackle the challenge of coordinating and managing multiple teams.

Why is it important?
In today's world, projects are often too big to be handled by a single team. LeSS offers a way to effectively scale Scrum way beyond single-team limits, promoting adherence to its core principles while managing greater complexity. It supports scaling of product development without adding unnecessary bureaucracy and management layers.

What is it?
LeSS is based on traditional Scrum, but expands it to large groups. Key features include feature teams, one product backlog, common sprint reviews and retrospectives. It comes in two flavours - LeSS and LeSS Huge, the latter being suitable for more than 8 teams.

How does it work?
LeSS applies the principles of Scrum on a larger scale. All teams work from the same product backlog, but have their own sprint backlogs. They coordinate their work but remain as self-managing as possible, with Scrum Masters playing a critical role in facilitating this process and removing obstacles.
