Abstract. Knowledge work is performed in all occupations and across all industries. The level of similarity of knowledge work allows for designing supporting tools that can be widely used. In this paper an activity-based perspective towards knowledge work is taken. Based on findings from a previous ethnographically-informed study, we identified valuable activities to be supported in order to increase knowledge maturing inside companies. The goal of this paper is to contribute to which knowledge maturing activities are deemed important, so that they can be supported by IT services. Quantitative and qualitative data have been collected in 126 organisations of different size, sector and knowledge intensity. Important feedback and issues emerged and need to be managed in order to support success in the knowledge maturing activities that allow improvement of organisational learning through the dissemination and application of the most appropriate knowledge.
