These days, Scaled Agile Framework (SAFe) is quite popular, because it is a freely revealed knowledge base of integrated patterns for enterprise-scale Lean-Agile development. It has the bright characteristics of a scalable and modular approach. Apparently, it allows an enterprise to leverage this model that suits their needs.

As a core principle, the SAFe framework synchronizes alignment, collaboration, and delivery for large numbers of agile teams in an enterprise.

SAFe has six core values in its design, which are as follows:

• Code quality
• Program execution
• Business alignment
• Transparency level
• Working model

The preceding diagram depicts the design of the SAFe framework.

It operates with common vision, architecture, and UX guidance. The fundamental theme is built around collaboration and adoption of face-to-face planning and retrospectives of the business. As part of the delivery, cross-functional agile teams deliver the working system increments every two weeks.

By implementation, there are two different types of SAFe: 3-Level SAFe and 4-Level SAFe. 3-Level SAFe is for smaller implementations with 100 people or less, or for multiple such programs that do not require significant collaboration. 4-Level SAFe is for solutions that typically require many hundreds of practitioners to develop, deploy, and maintain.
