+1 to H.Ozawa Are we talking (and Todd asks) about redundant resources, or operations, or functionality, or capabilities? Is it about competition, or failover, or disaster recovery, or geographical distribution of functionality?

By redundancy, are we talking about having multiple set of similar data/functionalitie s or about multiple set of similar business process? For example, if there are SAP app modules and Oracle app modules at a company without any overlapping modules but an overlap in common module functionalities, is there a redundancy. MDM and identity management reduces users from doing the same operations on multiple systems but IMO it doesn't really doesn't totally eliminate the data on multiple systems.
