Standardization is onemeans to realize scale economies, is prerequisite to automate the delivery of IT-services and hence a possibility to cut costs.Best-practice frameworks like ITIL also drive the standardization efforts by defining IT-service catalogues and standardprocesses. Upcoming or rather ongoing trends like on-demand computing require standardization to assure efficientallocation of resources.
