A successful computer system must have well trained users who understand they are the most import part of the system.
You can have the greatest computer system around, but it is not worth anything unless users are trained and made part of the team effort to implement and run that system successfully. Users need to understand the importance of their role in using their computers. They need to see how their role helps them in their particular job and how they fit into the overall picture. A user that feels that they are beneficial to the company and are part of the overall team effort will have a share in the common success of your computer system.
