Information system use is a primary measure of information system success. Information system use is a broad indicator that is often measured by frequency or voluntariness of use. While both of these measurements demonstrate use, they give no indication of how well the information system is used. Multidimensional use of information systems represents a more evolved, business relevant form of information system use. In this study, multidimensional use is use of an information system for the purposes of decision support, work integration, and customer service.

Intention based theories are used to predict and explain information system use. Individual difference is an external variable affecting beliefs that can influence how well information systems are used. In this study, individual difference is measured in terms of competency indicators, gender, education level, current job title, and years in profession as well as type of institution and shift worked.

Competency indicators are the independent variables of this study and the multidimensional use of information systems is the dependent variable. While support for the existence of a relationship between competency indicators and multidimensional use is inconclusive, significant differences in information system use were identified by job title and institution type. These findings have both academic and practical implications.
