In today’s economy, knowledge serves as an increasingly important asset and knowledge management practices have been widely implemented by firms of all industries. While knowledge integration (KI) has been recognized as a key component for the innovativeness of a firm, the concept has not been sufficiently researched yet. In particular, little is known about the role that individuals play in the KI process. This study seeks to advance the pertinent literature by exploring how individuals can be developed into more effective knowledge integrators. Conducting an action research project with a large Swedish car manufacturer, we draw from the field of psychotherapy, applying the Stages of Change model for behaviour change to the context of individual KI. Our main findings are that (1) organizations have to be wary of the risk of knowledge oversharing to limit the negative implication of KI, (2) employees are aware of the barriers that negatively affect the KI process in their organization, and (3) employees have to be brought to a stage of realization to learn how they would personally benefit from a more effective KI process.
