SAFe

Also known as: Scaled Agile Framework

Leffingwell's enterprise-scale agile coordination framework.

The Scaled Agile Framework was developed by Dean Leffingwell beginning in 2011 as a comprehensive framework for applying agile and lean practices at enterprise scale, with substantial elaboration through subsequent versions (SAFe 4.0 in 2016, 5.0 in 2020, 6.0 in 2023). SAFe organizes work across four configurations of increasing scope: Essential SAFe (single Agile Release Train, typically 50-125 people), Large Solution SAFe (multiple ARTs coordinated through Solution Trains), Portfolio SAFe (adds Lean Portfolio Management), and Full SAFe (complete framework). The Agile Release Train (ART) is SAFe's central scaling unit — multiple agile teams coordinated through Program Increment (PI) Planning events held quarterly, with synchronized iterations and aligned objectives. SAFe also defines Lean Portfolio Management, Value Stream Management, and DevOps practices integrated into the framework. SAFe is the most widely adopted scaled agile framework in large enterprises and government, particularly in regulated industries, but is also the most controversial — critics including agile-manifesto signatories argue it commoditizes and bureaucratizes agile in ways that contradict the manifesto's spirit, while proponents argue it provides realistic structure for enterprise contexts that simpler frameworks ignore.
