D. Research FrameworkThe framework for this research was built on the success model of DeLone and McLean information system which was the successful implementation of information systems proxied by user satisfaction [8]. In this study, researchers modified the DeLone and McLean model by issuing an intention to use (intensity of use) variable and use variable because SAP system was the ERP mandatory in Telkom. Livari conducted research to test the DeLone and McLean model on the accounting information system in the City Council of Oulu, Finland [10]. It indicated that the information quality has no effect on usage. Between variable of use and user satisfaction was not proven to mutually influence each other. The use of mandatory information systems cannot be used to measure the satisfaction of of the system users. User satisfaction was an attitude coming from within and was not happened because of coercion such as the implementation of mandatory information systems. Under these conditions, the variables that influence the success of information systems was the information quality as the output system, the system quality itself and the service quality. User satisfaction will ultimately have an impact on net Fig. 4. Research Framework Based on the framework and research model described previously, thus the hypothesis in this study were as follows: H1: The information quality positively affects user satisfaction H2: The system quality positively affects user satisfaction H3: The service quality positively affects user satisfaction H4: The user satisfaction positively affects net benefits III. RESEARCH METHODSA. Types of ResearchThis research was conclusive (causal) to investigate the influence of system quality, information quality and service quality for user satisfaction of ERP SAP system and its effects on net benefits on individual and organizational performance. B. Variable OperationalizationThis study used two types of operational variables, independent variables (exogenous) and dependent variable (endogenous). To measure each of the variables in this study, questionnaires were used. Statement in the questionnaire for each variable was measured by using Likert scale. The independent variables in this study were information quality, system quality and service quality. While the dependent variable in this study were user satisfaction and net benefits. The system quality was used to measure the quality of the information system itself [3]. System quality means the quality of the combination of hardware and software in the information systems. The focus was performance of the system, which referred to how good the capabilities of the hardware, software, policies, and procedures of information systems can provide the information needs of users [8]. Indicators were used to measure the quality of a system adapted from a research conducted by McGill et al [11]. The system quality in the research path diagram was abbreviated as KS. Information quality measured the output quality of the information system. According to Pitt and Watson in Radityo and Zulaikha [7], the information quality referred to the output of the system information, concerning the value, benefits, relevance and urgency of the information produced. In this study, this variable was measured by indicators used by McGill et al [11] and Wang et al [12]. The system quality in the research path diagram was abbreviated as KI. Service quality was the overall support offered by provider of information systems, ensuring information systems can be applied properly [2]. This variable was measured by indicators used by Chien and Tsaur [13] and Gorla et al [14]. The service quality in the research path diagram was abbreviated as KL. User satisfaction was response of a user after using the information systems [8]. Almutairi and Subramanian in Falgenti and Pahlavi [2] asked how effective and efficient the information system is and whether the user was satisfied with the system they used. The indicator used to measure user satisfaction was adapted from a research conducted by McGill et al [11]. User’s satisfaction in the research path diagram was abbreviated as KP. Net benefits were the benefits obtained after the use of information systems, both for individuals and organizations. Individual impact, was the effect of the use of information systems on the performance of individual user [8]. While organizational impact was influence of the information systems use to organizational performance [8]. Net benefits in the research path diagram was abbreviated as MB. tải về 195.75 Kb.
