With excellent information technology available today to manage data, why do organizations still have information deficiency problems

With excellent information technology available today to manage data, organizations still have information deficiency problems because of some technical problems. One of which is data silo where information will be trapped in the department's databases thus making it harder to share the data to other users. Other reason is the extensive changes in the required information that the management would require from the information system. This would happen if the information asked would be different from the standardized format of the system thus giving way to some deficiencies. Data lost and bypasses during transit is also a reason of this problem.
