Battling resistance

As an Administrator it is important to know and realize that no matter what you do, there will be some unhappy people.  How do you keep resistance to a minimum with technology?  By providing enough professional development to allow the teacher to learn how to use the technology.  It is also wise to ease into a situation to allow that teacher time to adjust.  At no point, should an administrator just send out an e-mail or memo and say start using this tomorrow.  Bringing technology in to the school should be a slow but goal oriented adventure.
