Evaluation of Enterprise Resource Planning (ERP) and Open-source ERP Modification for Performance Improvement

ERP system implementation in a company is based on business needs. The ERP usually used by companies is a commercial (paid/subscribed) ERP. The problems at PT XYZ are the decrease in user satisfaction with the performance of the commercial ERP system and the unavailability of access to modify the required modules. The purpose of this study is to evaluate the User Experience (UX) of the commercial ERP system at PT XYZ to determine user impressions and ratings on the performance of its use for business needs. UX evaluation is carried out using the User Experience Questionnaire (UEQ) method by measuring six aspects: attractiveness, dependability, efficiency, sharpness, novelty, and stimulation. The evaluation results that are measured are based on the mean value and also the benchmark of user experience. After the evaluation is successful, the results of the evaluation will be used as recommendations for improving the performance of the ERP system. Because there is no access right to modify the commercial ERP system, the recommendation will be carried out by modifying Odoo: open-source ERP that can be modified. The modifications are to adjust the aspects that still need to be improved from the evaluation results and add a new module that will be implemented to calculate sales commissions. The modified Odoo ERP System has been tested using the User Acceptance Test (UAT) method with a black-box testing model and evaluating user satisfaction using UEQ. The testing results got an Excellent benchmark value in attractiveness, efficiency, and novelty. In addition, there is a significant increase in value in other aspects compared to evaluating a commercial ERP system.
