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.

An object-oriented modeling approach is used to represent telecommunication services, parameters and calculation expressions associated with the parameters. Preferably, the Unified Modeling Language ("UML") is used in this regard. Further still, UML "sequence diagrams" are used to represent the calculation expressions as a sequence of UML methods that accomplishes what is required by the expression. The use of UML to represent calculation expressions simplifies editing and creating the expressions and permits a visual representation of the expressions.
