AIQA: A Tool for Information Quality Assurance in Post-implementation of ERP

摘要

Information Quality (IQ) a critical issue during the implementation of an enterprise resource planning (ERP) system;however, few have investigated IQ in the phase of the post-implementation of ERP. In this paper, the authors attempt to develop such a tool, which is called Activity-based Information Quality Assurance (AIQA) to form a basis for the systematic monitoring and evaluation of IQ. The tool encompasses a road map for defining, measuring, analyzing and improving IQ, an indicator system based on characteristics and logic-temporal sequences of processes, and a set of models to quantificationally describe the busniess process of post-implementaion. The tool is illustrated through a case study. The results of the tool are useful for reviewing and determining the best area for IQA activities.
