Description
A model is developed for assessing the data processing and data flow efficiencies of information and decision-support systems that have several users. The quality of the data is examined by the model at several processing stages, including the data at time of collection, input, processing, and output. The model is especially adept at identifying points in the system where errors could occur, and at assigning magnitudes to the potential error locations identified. “The model developed employs recursive algorithms to trace processing flows backward in order to determine higher quality processing alternatives with lower error ratios” (Harold, 1985). A computer based model will allow to experiment in a safe environment. Models are expressed in a variety of ways. These include, verbal, algebraic, graphical and statistical. It does not matter which way they are expressed as long as the model is:
• Internally consistent - possesses a logical argument which is correct and contains no mathematical errors
• Elegant - possesses a simple structure
