Cost-Reduction Strategies Consolidation
Reduces number of separate locations for information resources
Easiest to achieve in terms of information resources More difficult by end-user computing needs
DownsizingMigrating to smaller platformsAdvantage of cost reductionAdvantage of increased productivity with PCs located in user
areas Risk of lost security
Outsourcing Data entry and simple processing (editing, formatting) Contract programming Facilities management (FM) Systems integration (SI) Support for maintenance, service, or disaster recovery

Increasing Complexity of IM For the first 10 years or so of the computer
era, all the information resources were located in the firms information unit.
But as computer develops, more and more of the hardware are located outside of information services.
As firms acquire more information resources and as those resources are disperser throughout the organization, the task of information resource mgt. becomes complex
