Selecting the Optimal ERP Software by Combining the ISO 9126 Standard and Fuzzy AHP Approach

Abstract

ABSTRACT Enterprise resource planning (ERP) software is one of costly and crucial projects for business investment. Due to the selection criteria of ERP software are numerous and fuzziness, selecting the optimal ERP software is a critical process in the early phase of an ERP project. This paper presents a practical procedure which combines both the ISO 9126 standard and the fuzzy analytic hierarchy process (FAHP) approach to optimize the ERP selection problems. There are total 32 criteria sifted out which include 21 software quality criteria of ISO 9126 standard. Two practical cases which belong to different industries are applied to illustrate the practicality of the procedure, one is semiconductor manufacturing industry and another is chain store retailer service industry. We find that there are diverse weights for software quality criteria between these two industries. We also find that the cost issue and time issue are significantly important in both two cases.
