Nearly 50 years ago, John F. Kennedy asked Clark Clifford to handle his transition planning; the day after the election, Clifford handed Kennedy a single memorandum. Transition for today’s president-elect is much more complex. Managing the shift from campaigning to governing is the president-elect’s greatest challenge and biggest opportunity. According to Martha Joynt Kumar in her foregoing essay, the newly elected would do well to learn from the successes and failures of their predecessors. In short, the risks rooted in the inexperience and hubris of new presidents may be mitigated or avoided by knowledge gained from analysis of transition precedents. In this essay, the author provides a practitioner’s checklist of dos and don’ts drawn from his experience as a manager and advisor in presidential transitions.
