Failure issues is still important topic at IS field. This paper combination TAM model and culture dimensions as suggested model to predictable acceptance of usage the DSS. A possible contribution is to understanding the role of acceptance technology theory in systems usage, to explore national culture affected DSS usage. Researchers attempt to validate Hofstede’s national culture dimensions, TAM model for the case of usage of DSS and researchers extended technology acceptance model (TAM) as theoretical framework to test and predict usage of systems and to explore whether national culture influences users' perception where the People do things because they believe it is right thing to do. Keywords: Decision Support Systems, Technology Acceptance Model, national culture. 1. Introduction 30% of all software projects are cancelled, 50% come in over budget, 60% are considered failures by the organizations that initiated them and 90% come in late (Standish Group, 2004). Organizations make large investments in Information Systems (IS) expecting positive impacts to the organization. Failure issues is still important topic at IS field. The rate of information system project failure remains high in comparison with other high-tech projects. Although considerable effort has been devoted to improving the performance of information system implementations, organizations are still constantly suffering from the failures of information system implementations and is facing a variety of challenges, including the challenge of cross-culture management. The major problems with work performance and project failures are not technological in nature; they are sociological in nature (Kathy, 2007). Predicting IT adoption and use has been a key area of information systems research since the discipline’s beginning. Prior IS research has largely sought to explore how users come to adopt a particular IS. Most of these models are variants of social psychology theories that focus primarily on
