Moving your office from one part of town to the next can be very challenging. There are a lot of things that needs to be considered, there are a lot of factors that needs to be put on the table before success is reached.
This is very important as preparation can make or break your move. If you have a big project coming up, if there is something that needs to be done first settle it prior to moving. This will help you focus on the important things first. Moving deserves your full attention. If you can afford it, schedule it in time when there is not too much work that way everyone can prepare accordingly.
It is not enough that you have announced the date of the move. You have to coordinate as well. Remember that every employee needs to make their own preparations as well. Put up assign on your bulletin board, give out memo and remind each head in the office to remind their subordinates to prepare their own stuff, back up their files and so on.
