Developing ERP Post Implementation Success Framework through Group Decision Support Systems

Enterprise Resource Planning (ERP) success research is extensive and most approach models to measure its implementations success fall short of measuring post-implementation success. Instead of depending on previous frameworks that declare an ERP a failure if framework restrictions not met, this study suggests a novel methodology for assessing the implementation of any ERP method and its subsequent success via group decision support system. The study showed improved ERP system success when implemented with organizational culture improvement through GDSS but success was better when combined with access to more IT resources. There was improvement in Post ERP-implementation success (system quality, information quality, organizational impact, workgroup impact and individual impact) of the organization. Also, implementing ERP without GDSS does not reduces the success when it has access to IT resources. For ERP system post-implementation impact, IT resources capacity of the organization be improved and GDSS engaged to give users opinion.
