Certain user groups may possibly not be willing to relinquish control over their data to the extent needed to integrate data. Moreover, risk involved in data sharing, as in that one group may damage another group''s data and potential system problems that might limit a group''s access to its own data could be viewed as more troublesome than beneficial.

A project large in scope may be approximately impossible to complete in a reasonable time. Again, management and users become dissatisfied and project fails. Throughout course of a project, key personnel might unexpectedly leave a company. If replacement personnel cannot be found, then project might not be successfully completed.
