On November 8, the President-elect will begin the next phase of the transition to power that culminates with Inauguration Day on January 20, 2017. The next Administration will have a tremendous opportunity to drive change that improves mission performance across government, in ways that can positively impact millions of lives across the Nation across a broad range of mission areas – including health care for citizens, stewardship of natural resources, and delivery of benefits with financial integrity. To achieve outcomes quickly and effectively, new leaders will need to understand how to manage vast complexities in and across the agencies that implement policies and programs. Embedding management success at the highest levels of government should start during the Presidential Transition, and build through the first days of the Administration and beyond.
