company goals Long-term objectives Organizational structure Staffing and labor relations Crisis management Control of overall operations • Access to information from external sources Personal Computers Management • Benefits – Increased productivity – Independence from MIS department • Problems – – – – – – No one in charge of overall purchase of PCs Incompatibility Network related issues Needed data from MIS Training Inventory Personal Computers Management Solutions • Staffing – Personal Computer Manager – Network Manager • • • • • Acquisitions policies Information centers for assistance and training Use software to control inventory of PCs Remote access Consider total cost of ownership (TCO) Personal Computers Management • Personal Computer Manager – Technology overload – provide guidance to users for purchase and use – Data security and integrity – addresses the issues of who has access to what – Computer junkies – set guidelines for PC use • Network Manager – – – – – Operational Provide methods for sharing Install software Backup Network security Personal Computers Management Manager Characteristics • MIS background • Technical knowledge • Benefits and limitations of computers Personal Computers Acquisition • Standards – Hardware – Software – Data communications • Limit the number of vendors Personal Computers Information Center • Services – Software and hardware selection – Data access – Network access – Training – Technical assistance • Easily accessible location • “User comes first” Personal Computers Training Traditional approach – Sporadic participation – Minimal results for extended training Better approach – – – – – Initial training Home-grown gurus Follow-up support Involve the workers Web and CD based training Personal Computers Inventory • Budgets • Software – Count computers – Determines components – Determine installed software Personal Computers Remote Access • Equipment needs • Security concern • Training TCO Total Cost of Ownership • Initial hardware and software • Training • Support • Upgrading • Maintenance • Hardware • Software extras • Communications networks TCO estimated at four times the hardware costs! TCO Reduce the TCO • Limited Options – standardize the ordering process including hardware, software, and options • Helpful software – counts computers and determines their components and installed software in a networked environment • Hardware and software upgrades – insure there is justification for an upgrade Management Information Systems Leading Business into the Future
