A selected scenario of a design ICD document for an integrated enterprise is validated by examining each IDL call of each sequence diagram forming part of the selected scenario. A list of data attributes contained in one or more of the IDL calls are generated and each IDL call associated therewith is generated. A physical location to which each such IDL call is mapped is then associated with the IDL call. By analyzing the IDL calls and associated physical locations on a data attribute-by-data attribute basis, inconsistencies in the physical mapping of the data attributes to the databases forming an IIS for the integrated enterprise may be identified and subsequently corrected.
