The three levels of the Scaled Agile Framework are Essential, Large Solution, and Portfolio. These

levels represent the different levels of abstraction and complexity involved in delivering value to

customers. The Essential level is the foundation of SAFe and includes the Team and Program levels,

where agile teams and agile release trains (ARTs) work together to deliver solutions. The Large

Solution level is an optional level that supports the coordination and alignment of multiple ARTs and

suppliers that build large and complex solutions that require additional roles, events, and artifacts.

The Portfolio level is the highest level of SAFe and provides strategic direction, funding, governance,

and value stream management for the entire portfolio of solutions. Reference: SAFe® for Teams -
