The present paper is a research on problems of measuring Business Intelligence (BI) System Success. The well-known system of Information System Success by DeLone and McLean and Business Intelligence Capabilities Framework were reviewed to develop a framework for evaluating Business Intelligence (BI) Success. We hypothesize that BI Capabilities (Data Type Quality, Data Source Quality, Flexibility, Interaction with other Systems, User Access Quality) are positively connected with BI Success. Our hypotheses are tested with survey data. The respondents are CEOs, CIOs and BI specialists of Russian-based companies. Structural equation modelling exhibits a good fit with the observed data. Our results show, that BI Capabilities have a strong influence on BI System Success. However, there is more work to be done, because some hypotheses are not supported. The present paper contributes theoretically to Information System Success domain by expanding research about Business Intelligence System success.
