ERP systems improve productivity, but only to the extent that employees accept and use the systems extensively to perform their duties. The leaders of many organizations have not been able to realize the expected benefits because of a lack of user acceptance. The purpose of this quantitative cross-sectional survey study was to examine the factors that influence user acceptance of ERP systems in the United States. Davis’s technology acceptance model was the theoretical foundation used to relate the independent variables (perceived usefulness and perceived ease of use) to the dependent variable (user acceptance of ERP systems). The focus of the research questions was on the strength of the relationships between each of the independent variables and user acceptance of ERP systems in the United States. Data were from 97 purposively selected ERP system end users in the United States using the survey instrument based on the technology acceptance model. Regression and correlation analyses revealed a positive relationship between perceived usefulness and user acceptance, but no relationship was found between perceived ease of use and user acceptance. The findings indicated difficulties in using ERP systems for end users in the United States, which stakeholders could rectify to improve productivity in organizations. Positive social change implications include improving the standard of living, increasing the literacy rate, and reducing negative externalities to improve human and social conditions in society.
