Highlighting a critical yet often overlooked aspect of Lean implementation, this book discusses how to transform an organization from its current state to the desired state. Following the popular organizational approach of the prequel, A Tale of Two Systems, it presents two contrasting transformations based on polar opposites on the development spectrum: process-driven, compliance focused groups and chaotic groups. Synthesizing Lean manufacturing and Lean product development, it places agile software development in the context of Lean and examines the relative benefits of the Drive People versus the People Driven approach.
