The SAFe Framework
Scaled Agile Framework · v6.0What is SAFe?
The Scaled Agile Framework (SAFe) is a set of organizational and workflow patterns for implementing agile practices at enterprise scale — helping large organizations align strategy with execution and deliver value continuously.
SAFe was developed by Dean Leffingwell and Drew Jemilo, first released in 2011. It combines principles from Agile software development, Lean product development, and systems thinking into a comprehensive framework for scaling across teams, programs, and portfolios.
SAFe is built around the Agile Release Train (ART) — a long-lived team of Agile teams (typically 50–125 people) that incrementally develops and delivers solutions in a value stream. ARTs operate on a fixed cadence called the Program Increment (PI), usually 8–12 weeks, creating a predictable rhythm of planning, execution, and inspection.
The framework defines four configurations to accommodate different scales: Essential SAFe (the minimal starting point), Large Solution SAFe, Portfolio SAFe, and Full SAFe. Most organizations begin with Essential SAFe and expand as needed.
