As the de facto standard for object-oriented modeling language, UML is expected to play an increasingly important role in information systems development. The long-term viability and eventual success of UML depend, to a great extent, on the continued use by UML users such as developers and analysts. Systematic investigations on UML’s continued use have been missing from contemporary discussions. Our study attempts to fill this gap in the literature. We developed a research model, which is primarily based on the Expectation Disconfirmation Theory (EDT). According to this model, UML users’ perceived discrepancy between pre-adoption expectation and post-adoption perceived performance, which is conceptualized as performance disconfirmation and effort disconfirmation, is the determinant of satisfaction. UML users’ post-adoption expectation, in terms of perceived usefulness and perceived ease of use, is the determinant of attitude. Both satisfaction and attitude are posited as determinants of users’intention to continue using UML.
