Front-End Analysis: Generic and Nongeneric Models.
Abstract
Front-end analysis is described as an iterative process by means of which the requirements of a system may be made progressively more definitive. The importance of information to the process - whether it is obtained through an empirical study or from a generic data base - is stressed. The degree of detail with which system requirements may be specified depends on the level of information available at the time they are formulated. As specificity of system requirements increase, there may be a corresponding advance in the state of the system. The analysis process may be degraded by time-cost constraints, etc., the primary result being a reduction in the amount and quality of information needed by the analyst to determine system requirements and alternative action plans at adequate levels of specificity. It is agreed that this degrading effect of constraints may be minimized by an information procurement and management system that would make available to the analyst generic data. A number of models for front-end analysis that take advantage of generic data bases are presented within the context of training systems. Each is evaluated in terms of the gain in specificity of training requirements and instructional regimens that it may achieve relative to nongeneric analyses carried out under constrained and constraint-free conditions.
