Evaluation of an Existing Computer System Using Structured Analysis Techniques.

Abstract

This thesis is an evaluation of an existing computer graphics system using structured analysis techniques. The system evaluated is the IMLAC PDS-4 minicomputer. The technique used in the evaluation is performed in three steps. First, the existing system is modeled into its logical equivalent using bubble charts. This model shows the flow of data through the system, and the activities performed on that data. Second, a similar model is produced describing the required system as defined by the users. This model is a representation of the users' desires and requirements, and is similar to a model which might be produced during the requirements definition phase of a computer's life cycle. The third step is to compare the two models to evaluate the existing system's effectiveness, and reveal areas requiring modification for full utilizatin of the system. Following the evaluation, several recommendations and changes are proposed to increase the system's capability to meet the user requirements.
