Every complex project goes through turbulent or crisis phases. The book provides an introduction to the concepts of resilience and High Reliability Organizations. What characterizes high-performance systems? How do they "plan" for turbulence? How do they respond in crises? The H.A.P. model (High Adaptive Project) is presented, offering guidance based on the introduced concepts to make projects more resilient while also being flexible in the face of disruptive influences. The model is validated through interviews with project managers, executives, and department heads who share their experiences with highly complex dynamic projects and reveal their secrets to success in dealing with turbulence and crises. At the end of the book, a summary of the lessons learned is provided along with practical applications.
