Enterprise Resource Planning (ERP) systems have widely been applied by a lot of higher education institutions over the world; they have replaced their legacy systems to ERP systems due the integration advantages. Although, the institutions have a large investment with the ERP systems, there are several failed ERP attempts. Therefore, this work is interested in eveloping an appropriate model for evaluating the quality of ERP systems in the higher education institutions. Prior works on the software quality are reviewed and a comparison is made to identify best quality characteristics that should be used in evaluating the ERP systems. Interestingly, the ISO 9126 model has been adapted to evaluate the quality software of the systems, categorizing six quality characteristics including functionality, reliability, usability, efficiency, portability and maintainability.
