ABSTRACT
In order to relate expertise in business computer science to multiple criteria, the importance of competencies, as elements of expertise, for the performance of tasks and roles were investigated. Seventy-five information technology professionals (nine women and sixty-six men) from twenty-one organizations rated the importance of thirty-four competencies for the performance of eighty-six tasks and seven roles. In accordance with previous studies, knowledge of information technology, working methodically, and analytic ability were rated as important competencies for most types of tasks, and social skills were especially important for tasks related to interaction with the environment and leadership roles. By means of cluster analysis, four work domains were discerned: technique-oriented, organization-oriented, leadership-oriented, and user-support-oriented domains. It is argued that relating competencies to work domains has theoretical and practical relevance.
