This paper investigates the influence of a set of twelve knowledge sharing barriers of technological and organizational nature on the knowledge sharing performance (namely, speed and quality of knowledge sharing) in the administrative subdivisions in six of the leading Universities in Russian Federation. The barriers set included such barriers as: Low compatibility of document management systems used by a respondent and her colleagues; Insufficiencies of the document management systems used by a respondent and her colleagues; Complexity of learning to use these systems; Insufficient level of decision making authority delegation given by the senior management to the respondent and her colleagues; Insufficient clarity of instructions given by the senior management to the respondent and her colleagues; Too strict regimentation of job duties of the respondent and her colleagues; Insufficiently strict regimentation of job duties of the respondent and her colleagues; Lack of material remuneration for knowledge sharing; Lack of immaterial remuneration for knowledge sharing; Requested knowledge importance for its holder; Personal enmity; Time deficit to share knowledge due to work overload. The respondents have been answering the questionnaire including questions regarding perceived strength of the barriers by the respondent as the knowledge requester and knowledge holder. Thus, four models have been created: Barriers' influence on the speed of knowledge obtaining by request (Model 11); Barriers' influence on the quality of knowledge obtained by them by request (Model 12); Barriers' influence on the speed of knowledge sharing by the respondents by the colleagues' request (Model 21); Barriers' influence on the quality of knowledge shared by the respondents by the colleagues' request (Model 22).The models have been tested via the IBM SPSS Statistics 22 statistical package as linear regression equations. The results of this testing, showing the statistically significant influence of some of the barriers on the knowledge sharing speed and quality in different models, have been interpreted. On the basis of the educed results, several further research directions are suggested.
