Our mission is to serve the University through wise capital investment to meet the conflicting needs of minimizing initial capital outlay and maximizing length of trouble-free service.

PC Quality Considerations

1.      Two different markets - Business and Consumer

Name brand computer manufacturers supply computers designed for (at least) two different markets with different requirements for reliability.

 

Manufacturer

Business

Consumer

Dell

Optiplex

Dimension

Compaq

Prosignia

Presario

Hewlett-Packard

Vectra

Pavillion, Brio

 

         Computers designed for home use typically are used for fewer hours in the day, with less demanding applications such as email and word processing, usually in a standalone environment.

         The impact of computer failure is less severe at home than in an office where the machine plays an integral part in accomplishing the day's work.

         Computers designed for business use are engineered with components of better quality and tested to work together in a variety of situations, including reliable operation over a network.

2.      Total Cost of Ownership (TCO)

Many studies have been done on cost of owning computers, and these reveal that hardware and software capital expenses account for about 25 percent of the total cost of deploying and owning computers. "Most costs are associated with management and technology support by IS professionals, and the hidden costs of end-users managing and supporting their own computer systems." Interpose, Inc.

The impact of downtime will vary according to the circumstances. However, the higher risk of failure that is inherent with lower quality machines increases the risk that interruption to service might create an unhappy student or turn away a potential student.

3.      Hardware Component Specifications

Dan Widner (ITS Client Services) has prepared a document outlining hardware components that are required to meet minimum levels of reliability and networkability.
