Behavioral
Considerations
A new information system creates new work relationship among existing
personnel.
It creates changes in job content and perhaps a change in the formal
organizational structure.
The user cooperation needed to operate the system successfully should be
ensured during the design of a system, not afterward.
A philosophy of user-oriented design fosters a set of attitudes and an approach
to systems development that consciously considers the organizational context.
Another response which depend on personality, experiences, support,
communications, bias, refusal, fearness etc.
