How Effective Managers Use Information Systems
Computerized information systems do much more than save managers time and money. They also improve managerial effectiveness. Management decision support systems range from systems that retrieve and analyze data to systems that evaluate decisions using accounting, simulation, optimization, or actuarial models. Managers use these systems as tools of persuasion, as tools of communication, and as a means of increasing organizational control. A study of 56 systems shows that a system has a greater probability of being successful if the end users participate in its development and implementation.
