Existing wellknown EAM systemssuch as select component architectcasewise and adaptive systernsare contentcentric(mashing up heterogeneous data sources)and thus become large repositoriesSuch approaches are also timeconsuming because of the need to manually map information to ensure that it is provided to the corect userZachman f2005)considered that time consumption was one of the most important issues in EASeveral questions relating tousercentric' focused inform ation interoperability and inform ation governance(ECU2008)have not been clearly answered in the existing EAM literature
Governance perspectiveHow can certain top or middle managers(plannersdesignersconstructorsadministrators managersetc1 be enabled to understand the needs of enterprise users and the value (usefulness)of crossfunctional information assets?How can the functional scope and resDonsibilities of enterprise users be definedand classified?(Who iS jnvolved in what?W ho owns what?And who wants what?)
Interoperability perspectiveHow would certain users(inform ation consumers)experience information interoperability among enterprise systems to perform their tasks?
Interoperability and governance perspectiveHow can users'needs and expectations about the info rmation assets that an enterprise has to ofrer or may provide be matched for effective operation?How can inform ation resources(productsservices)be accessed by certain users(policies and access rights)?Have alternative information resources been considered for enterprise users across different domains?Existing EAM Ss have limitations in answering these questions
Most EAM S models are either too complex or too simple(1acking required features)to implement and do not foCUS on solving the enterprise users'business problems oil a runtime basis
