Abstract
Enterprise resource planning (ERP) systems are complex software packages that support
an integrated real-time setting among the various business functions in an entire
organization. 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.
