Arussy: In our research, we were surprised to see that executives placed time, budget, and governance models at the bottom of the “obstacles” list. When you look at the top four or five obstacles to change, all were human-related factors. People in the organization didn't understand the “why.” Senior leadership didn’t communicate effectively. Senior leadership was not aligned behind the change. That’s why this book is so different, because it emphasizes the human factors, the psychology, that are at the center of the struggle to change. Budgets and technologies aren’t the main challenges, people are.
