The Scaled Agile Framework® (SAFe®) is a set of organizational and workflow patterns for implementing agile practices at an enterprise scale. The framework is a body of knowledge that includes structured guidance on roles and responsibilities, how to plan and manage the work, and values to uphold.
SAFe promotes alignment, collaboration, and delivery across large numbers of agile teams. It was formed around three primary bodies of knowledge: agile software development, lean product development, and systems thinking.
As businesses grow in size, SAFe provides a structured approach for scaling agile. There are four configurations in SAFe to accommodate various levels of scale: Essential SAFe, Large Solution SAFe, Portfolio SAFe, and Full SAFe.
