Large-Scale Scrum

Large-scale Scrum (LeSS) is a product development framework that extends Scrum with scaling rules and guidelines without losing the original purposes of Scrum.

Snippet from Wikipedia: Scrum (software development)

Scrum is an agile framework for developing, delivering, and sustaining complex products, with an initial emphasis on software development, although it has been used in other fields including research, sales, marketing and advanced technologies. It is designed for teams of ten or fewer members, who break their work into goals that can be completed within timeboxed iterations, called sprints, no longer than one month and most commonly two weeks. The Scrum Team track progress in 15-minute time-boxed daily meetings, called daily scrums. At the end of the sprint, the team holds sprint review, to demonstrate the work done, and sprint retrospective to continuously improve.
