LeSS is Scrum—Large-Scale Scrum (LeSS) isn’t new and improved Scrum. And it’s not Scrum at the bottom for each team, and something different layered on top. Rather, it’s about figuring out how to apply the principles, purpose, elements, and elegance of Scrum in a large-scale context, as simply as possible. Like Scrum and other truly agile frameworks, LeSS is “barely sufficient methodology” for high-impact reasons.
