More than a guide, this book shows, in a simple way, attitudes and behaviors expected by someone who is part of PMO projects in large corporations and organizations, showing that this fight is not about how hard you can hit, but how much you can get hit and keep moving forward to deliver the project in a successful way. Thousands of variables are found on projects so that they are delivered on time, on the combined cost and with the expected quality. The greater the project complexity, greater the obstacles to achieve the proposed objective tend to be. In this context, the Project Manager will need to count on the unconditional support of the PMO (Project Management Officer), whose mission is entering the ring project in a way that both come out victorious.
