Answer:
Develop Campaign Policies Into Actionable Items: Staff work on developing the campaign pledges a certain candidate has made into federal policy and legislation so proposals can be worked on as soon as the President is inaugurated. Likewise, in the short time after Inauguration, a President must deliver a State of the Union, present a budget, and detail a larger agenda for the first several months of their presidency. Work months before is crucial. Also, during this time, staff review the work of the various agencies to see where specific priorities fit and where “flashpoints” exist.
Political Appointments: The President has the authority to nominate or appoint at least 4,000 government positions. One thousand of these require Senate confirmation. The transition team tends to vet Cabinet-level and key deputies early on, as well as key White House personnel. Other important positions that the team vets are Deputy Secretaries, Under Secretaries and Assistant Secretaries. Later on in the process, usually after the election, they start to vet certain Schedule C appointments. These are positions that serve at the pleasure of the President and do not require Senate confirmation.
Operational and Logistical Support: The official transition team of the President-elect gives operational and logistical support in the months before Inauguration. They are assisted in things such as office space, human resources, and communications, IT support and congressional and other outreach work. Also, transition teams work to develop a legal infrastructure, including such items as who can serve in an Administration (i.e., any ban on lobbyists comes through this process).
