Studies in business intelligence systems has earlier focused on the success of implementations and how the system satisfies the end-user. This study therefore examines how users characteristics affects how they perceive business intelligence systems as easy of using and useful. Furthermore, perceived ease of use and usefulness in the business intelligence system and how this affects the ability to meet performance targets at unit level is examined. The study had a quantitative approach and was carried out with the help of a survey where 91 respondents participated. All respondents are working as head of units in a company applying business intelligence systems in their daily activities as a way to control and support decision making. The collected data of the study were analyzed by using a path analysis and multivariate regression. Cronbach’s alpha was used to test the measures reliability. The results show that on a high significant level, both perceived ease of use and usefulness correlated with how performance targets are achieved. The results also showed that when the business intelligence system is perceived as easy of using and useful, decision is made with higher quality. The results provide indications for how companies should work with these components and thereby control the organizations results in a better way.
