Verification of vertical time lag in an e-government system by using a casual model: Korea worknet system case

Abstract

Many organizations and governments have been investing various types of innovative information systems. Sometimes it takes time to see the performance of such investments due to the time lags. The time lags of information systems investment can be seen from vertical and horizontal viewpoints. The vertical means the time lag among the performance layers; input, process and output and the horizontal means the time lag in a specific layer. In this study we show the existence of time lags between the layers by using causality relation model for the WORKNET system of Korea. For this study we made indicators for each layers and tested the causality among indicators in different layers. From this study we showed the existence of the time lag between performance layers.
