Most implementations will see a lot of time and effort going into preparations for eventual users. Training programs often begin well before systems are even finished, and the input of end users can be invaluable when it comes to ensuring that ERP applications can be quickly and easily used by employees. However, the problem that often arises is knowing who the end users will ultimately be. Obviously some of them are going to be the workers at a particular company, but there could be external collaborators and even customers who will eventually need access to company data on occasion. Be sure to take into account a particular enterprise’s practices to determine if this will be the case.
