LeSS is a lightweight (agile) framework for scaling Scrum to more than one team. It was extracted out of the experiences of Bas Vodde and Craig Larman while Scaling Agile development in many different types of companies, products and industries over the last ten years.
LeSS consists of the LeSS Principles, the Framework, the Guides and a set of experiments. The LeSS framework is divided into two frameworks: basic LeSS for 2-8 teams and LeSS Huge for 8+ teams.
This introduction to LeSS tells the story of how LeSS evolved out of the early experiments from Bas and Craig.
