The attached document provides both an executive summary and detailed analyses of lessons learned from the Constellation Program. It is a companion document to Constellation Program Lessons Learned Volume I. The topic areas discussed include: Roles, Responsibilities, Authority, and Decision Making; Requirements; Data Management; Schedule and Resource Management; Joint Confidence Level; Construction of Facilities; Risk Management; Design and Development; and International Partner Development.

The character of these lessons is worth noting. The reader will observe that very few technical issues arose that could not be solved in relatively short order; rather, the most difficult and most persistent challenges involved cost, schedule, and organization. The reader will no doubt recognize this pattern from previous large-program lessons learned. While the Agency is renowned for its technical prowess, senior managers in flagship programs can be faced with a multitude of nontechnical challenges for which they have far less training or preparation. In this respect, lessons learned can be an invaluable source of insight.
