Two reasons the Agile Manifesto for Software Development is still relevant to Lean-Agile Enterprises are:

It provides the foundation for empowered, self-organizing Agile teams. The Agile Manifesto values individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan1. These values support the creation of cross-functional, autonomous, and collaborative teams that can deliver value to customers and stakeholders in an agile way2.

SAFe extends the value system and principles of the Agile Manifesto to teams of Agile teams. SAFe is based on the Agile Manifesto, but also incorporates additional values and principles that address the challenges of scaling agile to the enterprise level3. SAFe values alignment, built-in quality, transparency, and program execution, as well as the four original values of the Agile Manifesto4. SAFe also applies nine additional principles that guide the behavior of teams of Agile teams, or Agile Release Trains (ARTs), in a Lean-Agile context5.
