This paper examines barriers to adopting competence systems in knowledge work practice. On the basis of a technology review and a user site investigation, the paper relates the technical features of the investigated competence systems to the adoption barriers identified in six user organizations. The multiple-case study shows that the competence systems can be described as merely traditional personnel administration systems complemented by features that passively archive formalized descriptions of competencies. Building on this observation, the general objective of the paper is to provide design suggestions that facilitate successful integration of competence systems in organizations. The main conclusion of this paper is that competence systems need to have features conveying a technology spirit more in line with the knowledge work practice found in organizations. By researching competence systems and their features specifically, this paper contributes technology-specific knowledge within the area of knowledge management systems.
