Example text

For instance, in an automated teller machine, we wish to study the usefulness of fast service features, such as providing cash or set amounts of funds quickly after the amount has been typed in. We may decide to ignore details of the ATM's internal operations or user changes. 7 Overview of performance evaluation methods 27 The model would be the bank teller machine, its interface, and a model (analytical, simulation) of the internal process. The experiment would be to have users (experimenters) use the model as they would a real system and measure its effectiveness.

Using these techniques, the analyst can suggest changes and improvements and predict their impact based on real information. 8 Performance metrics and evaluation criteria Selecting a computer system architecture and system support software requires performance metrics and evaluation criteria. In order to generate such information, a user must follow a methodology of selection that defines the user needs, the motivations, and the environmental and technological boundaries. As with the purchase of any product, the purchaser should identify how the product (in this case a computer system) will be used.

To alleviate these problems, the users should be educated about the basics of computer architecture, operating systems, database systems, and local area network technology and be provided with metrics and tools with which they can adequately wade through the myriad issues and select a computer system mapped to their needs. 6 Role of performance evaluation in computer engineering 23 When you look at the many options available for prospective computer systems purchasers to evaluate, you can see the reasons for their distress.
