Studying enterprise systems' acceptance using integrated unified theory of acceptance and use of technology (UTAUT)

This paper proposes framework within unified theory of acceptance and use of technology, task-technology fit and perceived trust to reposition consumer-context and assure need-fit and security in enterprise system adoption. Survey data were collected from a purposive sample of 191 executives of fast-food firms, and analysis and empirical findings were based on multiple regressions and partial-least square. The results indicate that within the proposed framework, an approximated 57 percent of variance on ES adoption was explained by the predictors with acceptable fit indices and significant relationships between variables. All the path coefficients were statistically supported with the paths of facilitating conditions and task interdependence to adoption being the most critical predictors, and complexity to adoption having a negative significant coefficient-a unit increase attracts less adoption likelihoods or vice versa. The integrated model is critical to the understanding of ES adoption and implies on the operational ordeals of the individual models and reinforces improving skills and infrastructural facilities, interpersonal communications amongst audiences, and service quality to reflect trust and task demands.
