Abstract

In order to survive in today’s global competitive environment, businesses have to use information systems during management and production processes. Technology Acceptance Model (TAM) is developed by Davis (1989). According to this model, the use of a new information system depends on perceived ease of use and perceived usefulness variables. This study analyzes the factors that affect the use of Enterprise Resource Planning (ERP) software, which is an information system, in the frame of TAM variables. 236 companies that use these information systems participated in the survey. It is determined that, eleven independent variables, which are taken into consideration in the scope of user characteristics, innovative characteristics, organizational and environmental characteristics factors, have statistically meaningful and positive effect on perceived ease of use and perceived usefulness which represent TAM parameters. Similarly, it is determined that, perceived ease of use and perceived usefulness have a positive and statistically meaningful effect on the use of ERP.
