In a society dependent on knowledge, information and information technology (IT), studying IT-oriented knowledge intensive firms becomes particularly interesting. Previous research has for the most part studied management consulting firms as well as how knowledge management and knowledge management initiatives can support or inhibit the growth of organizations. To further progress this line of research the study intends to fill a gap in research concerning consultants focusing on IT-solutions. Consequently, this study has two equally important purposes. Firstly, the study intends to investigate the application of Ikujiro Nonaka’s Organizational Knowledge Creation Theory on new empirical data. Secondly, this study aims to explain learning processes in the IT-consulting trade. The empirical data used is taken from eight interviews and three qualitative surveys from three different IT-consulting firms in Sweden. By using a multiple-case study design this study simultaneously presents a broad perspective of the IT-consulting trade and a deeper understanding of the knowledge sharing processes used in the different cases. The study has resulted in three major conclusions. (1) There are different types of digital tools that are important for knowledge sharing in organizations. These are digital conversation-rooms, digital pin boards and internal databases. (2) The authors also identify six conditions that are important for knowledge sharing. These conditions are proven to have a complex relationship with the context in which knowledge is shared and the consultants’ choice of digital tools. (3) Lastly the Organizational Knowledge Creation Theory is found to be insufficient in describing the knowledge sharing processes in IT-consulting firms, especially regarding the relation between the socialization and externalization processes. Proposals for future research in relation to the findings are presented.
