A very large percentage of information systems fail to deliver benefits or solve the problems for which they were intended because the process of organizational change surrounding system building was not properly addressed. The principal causes of information system failure are
• Insufficient or improper user participation in the system development process
• Lack of management support
• High levels of complexity and risk in the systems development process.
• Poor management of the implementation process
There is a very high failure rate among business process reengineering and enterprise application projects because they require extensive organizational change that is often resisted members of the organization. Enterprise applications as well as system changes resulting from mergers and acquisitions are also difficult to implement successfully because they usually require far reaching changes to business processes.
