This paper aims to propose a framework for assessing information system (IS) success considering the impact of culture. Previous frameworks for assessing information system (IS) success, such as DeLone and McLean model, only concern about the status of IS implementation itself. But none of the models have included the dimensions for assessing culture even though researchers have shown the strong relationship between culture and the success (or failure) of the IS. The inclusion of culture in the IS success model is very important, especially in Indonesia, since culture plays as a dominant part in almost all aspects of citizen’s lives. This paper is expected to make a contribution on providing a framework for assessing IS success considering the impact of culture. To validate the proposed model, a mixed-method research design is proposed.
