As more and more people are required to use computers as part of their jobs, ends user organisations are generating more computer jobs to support these day-to-day activities to modify systems, to investigate new ones, to train users, to specify new equipment needs and to interact with suppliers.

End user organisations embrace all types of employers in both the public and private sectors.
