This document introduces the Scaled Agile Framework (SAFe) as an approach for applying Agile and Lean principles at an enterprise scale. It discusses how traditional development methods are not keeping pace with increasing software complexity. SAFe is presented as a proven framework that harnesses the power of Agile for large software enterprises through elements like Agile teams, program execution, alignment, code quality, and scaling practices up to the portfolio level. The document advocates for SAFe's ability to accelerate value delivery, make money faster, deliver better customer fit, and reduce risk through approaches like continuous delivery, cadenced development, and synchronizing teams.
