Why an information gap exists in most organizations
Give details why an information gap exists in most organizations?
Expert
The main reason for the existence in an information gap is the fact that systems have been developed in separate, segmented efforts. This has assisted the data from being stored in an integrated database and therefore the data is in an inconsistent structure. Another reason for the gap is that most systems are created to support the operational aspect of an organization. The systems were not made for decision making.
