This document summarizes the results of a study on knowledge maturing activities and practices that foster organizational learning. Interviews were conducted with companies across Europe to understand how they assess the importance of various knowledge maturing activities, barriers to those activities, and differences in approaches. The results show that reflecting on work practices, finding expertise, and sharing resources are among the most important activities. Companies tend to cluster into groups that are people-oriented, hesitant about formal processes, or focus on distribution. While restricting access to knowledge is controversial, perspectives differ at the organizational and individual level depending on factors like trust, information overload, and competitive advantages. Overall, the study provides insight into supporting knowledge sharing and maturing in professional contexts.
