Trump can start reorganization without confirmed positions.

 THE PRESIDENT HAS THE POWER TO MAKE DECISIONS WHILE POSITIONS ARE VACANT

TRUMP LIKES TO KEEP BUSY

It is expected that many will attempt to slow walk Trump's appointments. While that may be an attempt to slow down his agenda, it by no means needs to be a major obstacle in beginning reform or implementing his agenda. 

The President has the authority to name an interim head of every department, and I suspect other key people in a department, they usually just require that they are a former head or have worked in that department. While the qualifications are vague, objections will need to go through a legal process which may take far longer than the confirmation process.

The other option is that Trump can personally start making decisions for certain departments, he does not need to be confirmed, that happened last November. He can also use a lot of assistants and interns to observe actions in these departments and report directly to the President. The President can then take actions on those who are not implementing his directives. The President can show up at these offices with his staff and begin making decisions anytime after Jan. 20. 

As for the state department and other foreign policy appointments, Trump can use the time zone differences to work through the night, personally talking and negotiating with foreign leaders. It is well know that Trump sleeps very little and we can expect he will be anxious to fit as much as possible into his 4 years.

He would be wise to use the bully pulpit to be as transparent as possible with his activities and progress, maybe a weekly address or a bi-weekly press conference. He can then blunt the spin and narrative that will likely be used to cast a negative light on his methods.

One more month and it will all begin.
