Before the release of the versions SAFe 5.0 and SAFe 6.0, there were three levels of the Scaled Agile Framework– Team Level, Program Level, And Portfolio Level.
However, these levels were not sufficient to provide solve all the problems and drive business agility. So, a new level called Large Solution Level was later added to the SAFe version 5.0. All the levels on the SAFe framework help to provide value through a centralized approach that aligns with the business goals.
