Book excerpt: This book presents a model of organization transformation success. The model framework comprises a series of S-Curves (maturity curves) of planning and execution activities phased over time. The model is illustrated through description and analysis of an actual, two-decade, highly successful, global enterprise transformation Six Sigma program at a Fortune 200 company: Cummins, Inc. Lessons learned from the model and company case study are completely transferrable to other organizational culture, improvement and innovation transformation settings. This insightful book: • Documents a firsthand account of a successful transformation. The authors completely explain what was accomplished and the lessons learned from a 16-year deployment of Six Sigma at Cummins. • Acts as a benchmark for those organizations interested in pursuing primarily a continuous improvement transformation, and more generally for other types of transformation efforts. • Includes substantive interviews with ten key leaders and others who made the transformation possible. • Helps organizations shorten the overall transformation timelines. The documentation of a transformation provides you a model for how to think about organization transformation maturity over time and plan for it. • Recognizes the work of thousands of people involved in transforming a global company. The interviews provide extraordinary perspectives not only by executives who initiated and sustained the transformation program but also by program participants who themselves grew as managers and leaders in their careers through the program. Essentially, this book helps early-career managers and executives see the broader picture of enterprise transformation, especially over time. This helps them be better managers and executives, and importantly, helps them better plan for and hasten their upward career trajectories. Lastly, the book describes a view of possibilities. It describes a clear, sustained success, the steps taken to get there and the measurement of progress. The result provides you with confidence that successful transformation is possible and worth the effort.
