Abstract
The purpose of this research was to analyze the appropriate factors of the information system used in the operation of the department. And to check the consistency of the appropriateness model of the information system used in the operation of the department.The sample group is the users of information systems of the Faculty of Business and Information Technology, Rajamangala University of Technology Suvarnabhumi, Academic Year 2017, 300 people were selected by multi-stage random sampling. The tool used was a questionnaire for the appropriateness of the information system used in the operations of departments in the Faculty of Business and Information Technology. Basic statistical analysis by using statistical data analysis program and confirmed component analysis to check the structural validity of the model, the components, the appropriateness of the information system used in the operation of departments in the Faculty of Business and Information Technology. The results of the research revealed that the suitability of the information system used by the work units in the Faculty of Business and Information Technology consists of 8 components. The composition weight is between 0.43 to 0.88. Rankings can be ranked according to the composition weight. As follows: Systems Reliability, Production Timeliness, Relationship with Users, Ease of Use / Training, Authorization, Compatibility, Locate ability and Data Quality. The model of the information system used in the operation of the department was found to accord with empirical data. Goodness of fit indicators included a chi-square value of 17.59 with 11 degrees of freedom: p =0.092, RMSEA = 0.047, SRMR =0.018, GFI =0.98, AGFI =0.95, NFI = 0.99 and NFI = 0.99.
