Building upon well established Scrum, XP, and lean software development methods, agile scaling frameworks such as Dean Leffingwell's Scaled Agile Framework (SAFe) and Scott Ambler's Disciplined Agile Delivery (DAD) address large, complex software delivery initiatives through their full delivery lifecycle from project initiation to production. These frameworks have received significant interest in both federal government and private industries, recognizing the need for continued team-based iterative and incremental adaptive approaches to software development, balanced with scaling processes and factors at the Program and Portfolio levels and organizational governance models and guidance for large enterprise engagements. This session will provide a brief overview of these two agile scaling models, address the benefits of what both are trying to accomplish, and compare and contrast specific similarities and differences.
