1.  Management buy-in!!  Into the ERP system and the implementation process.  (I cannot stress this enough)

2.  Map your existing system’s database fields with that of the new systems’ as soon as possible.  Attempt to automate the ‘re-load’ of data.  Then make the data visible to users – they’ll love seeing “their” data.  (This will improve Change Management).

3.  Make key users responsible for Master File integrity.  Yup, accountability!  A pain, but worth it.

4.  Make the key processes work first – then the bells and whistles.  Document them, set target dates and track them!  Have the key users test them.
