 # Less
+
+**LeSS** (Large-Scale-Scrum) is an agile framework designed to scale Scrum across multiple teams working on a single product. It adheres to Scrum's principles, emphasizing simplicity and continuous improvement. LeSS encourages coordination between teams by using a single backlog and a common Product Owner. Each team is responsible for parts of the product, but they collaborate in its joint development, with frequent feedback loops to adjust project direction. Its goal is to minimize bureaucracy and maximize value delivery in an agile and efficient way.

+**SAFe** is an agile framework designed to scale agile practices in large and complex organizations. Unlike LeSS, SAFe is more structured and provides a formal approach to coordinating multiple teams, programs, and portfolios. It incorporates elements of `Lean`, `DevOps`, and `agile principles`, and defines additional roles, ceremonies, and artifacts to align teams' goals with the business strategy. SAFe enables **large-scale planning**, **continuous delivery**, and **improvement of organizational efficiency**, offering a comprehensive framework for agile transformation at the corporate level.
