Final answer:
The Scaled Agile Framework (SAFe) 4.5 consists of four levels: Team, Program, Large Solution, and Portfolio, which help large organizations align and execute their work efficiently.
Step-by-step explanation:
The four levels of the Scaled Agile Framework (SAFe) 4.5 are essential for large organizations that need to coordinate multiple teams and projects towards a unified goal. The four levels are:
- Team Level: At this level, cross-functional teams plan and deliver work in regular iterations, often with a focus on working in a Scrum or Kanban style.
- Program Level: This is where teams are organized into larger 'Agile Release Trains' (ARTs) which plan, commit, and execute together.
- Large Solution Level: This level deals with additional complexities of developing large, integrated solutions which typically involve multiple ARTs and suppliers.
- Portfolio Level: At the portfolio level, the focus is on investment funding, large-scale value streams and portfolio governance to ensure alignment with the enterprise's strategic themes.
These levels ensure that coordination and collaboration occur across various levels of an enterprise, leading to better efficacy in project completion and revision through learning.
