The transfer of tacit knowledge, one of the most important issues in the knowledge sharing context, needs a multi-dimensional perception in its process. Information technology's (IT) supporting role has already been addressed in the process of tacit knowledge transfer. However, IT has its own characteristics, and in turn, may have dissimilar support suitability. On the basis of the knowledge transfer process proposed by Garavelli "et al." (Garavelli, C., Gorgoglione, M., Scozzi, B., 2002. Managing knowledge transfer by knowledge technologies. "Technovation" 22, 269-279), this study conducts an assessment using the analytic hierarchy process (AHP) technique to disclose (1) importance rank of transfer stages for the transfer efficacy and (2) the support suitability of IT types for the transfer stages. The assessment hierarchy has three levels, which are the goal, process and support levels. According to the 21 domain scholars and specialists' assessment analysis, the main results suggest that (1) for goal level, both the knowledge provider's and receiver's cognitive system are of more importance, (2) for process level, database techniques and information system applications obtain the higher importance in supporting the provider's cognitive system and externalisation, and (3) software tools and information system applications are more likely to support the receiver's cognitive system and interpretation. Discussion and implications are also addressed. (Contains 4 tables and 3 figures.)
