Evaluating the Quantitative Effects of Workflow Systems based on Real Cases

The effects of introducing a workflow system include improved work efficiency, reduced processing time (that is, turnaround time), standardized business processes, and made processing paperless. However, no concrete methodology for quantitatively evaluating these effects has been established. In this paper, by analyzing some examples of introducing workflow systems, we extracted the factors that influence the effects, and we used quantification theory type I to create a mathematical model for predicting the rate of reduction of processing time as an effect of introducing a workflow system. As a result, we concluded that (1) the process improvement and (2) business process classification before the introduction of the workflow system as the factors that influence the effects. As a predictive model, multiple correlation coefficient R is 0.932, showing that the two factors have a considerable influence.
