This is the complete guide to using the Scaled Agile Framework® (SAFe) to achieve agility at scale, successfully transform software organizations, and deliver better software. Leading enterprise development expert Dean Leffingwell helps you implement lean/agile principles in organizations of any size or complexity, overcome barriers to agility, and apply lean thinking to continually improve all aspects of software delivery. You'll learn how to use SAFe's "Big Picture" user interface to understand and optimize every role, team, activity, and artifact needed to scale from team to program to portfolio. Leffingwell helps you scale key agile elements of value (requirements and Backlogs), teams (from development team through Portfolio), and Timebox (iteration, PSI, budget cycle). You'll master techniques that have been successfully applied by development teams ranging from 50 to thousands of professionals, at enterprises including Nordstrom, Visa, John Deere, HP, Intel, Capital One, and Comcast. If you need to achieve agility at scale, no other methodology competes with SAFe, and no other book offers as much practical guidance for succeeding with it.
