Abstract

This study aims to develop and implement a new Technology Acceptance Model (TAM) to verify and explain users’ acceptance of SAP software. The structural equation model (SEM) technique is used with the AMOS program for the adoption process. General structural model, which includes Experience, Voluntariness, Perceived Enjoyment, Perceptions of External Control, Computer Self Efficacy, Output Quality and Job Relevance, is developed with Analytical Hierarchy Method (AHP) and Pareto Analysis by deciding variables from previously original developed models which are called TAM1, TAM2 and TAM3. New TAM is tested to a sample of 384 SAP users in a company that serves in metal production. Results illustrates that new TAM is an appropriate tool to explain and understand users’ acceptance of SAP besides of being flexible and easily implemented. SAP users’ job relevance and their perceptions of external control are the most important variables that affect perceived usefulness and perceived ease of use in the model.
