Knowledge has become one of the key strategic assets for the organizations to gain and main-tain competitive advantage.

Tacit knowledge is Omni present in indi-vidual’s head while explicit knowledge is a written and documented. The most valuable and remarkable human knowledge exists more implicitly. Sharing and managing this implicit knowledge is considered very difficult, so investigating the factors that may affect knowledge sharing has become a colorful area of research. The focus of this study is to examine the relationship between individual (individual attitude, organizational commitment, and knowledge self-efficacy) and tacit knowledge sharing. The study distributed 650 questionnaires among teaching staff in public higher educational institutes. Out of 650, only 320 questionnaires were returned. Hypotheses for direct relationships were tested using SEM. Results indicated that individual attitude and knowledge self-efficacy were substantially associated with tacit knowledge sharing, however, no relationship was found between organizational commitment and tacit knowledge sharing.

Therefore, the current study's purpose is to explore the influence of cloud computing services on Jordanian commercial organizations’ competitive advantages, organizations which use cloud computing services. The study uses quantitative, cause-effect, and cross-sectional methods and uses a convenience sampling approach to collect the data by questionnaire from 111 managers and/or owners of commercial organizations. The collected questionnaires are examined and inserted into SPSS. The instrument validity, normal distribution, and reliability are verified, then descriptive analysis is performed, the relationship between independent and dependent variables is tested, and finally multiple regressions are used to test the hypotheses. The findings indicate that commercial organizations are concerned about cloud computing services as well as competitive advantage sub-variables. The results also show that there was a significantly strong correlation between cloud computing services and competitive advantage. Moreover, cloud computing services influence the dimensions of competitive advantages (quality, cost, reliability, innovation, and responsiveness) of commercial organizations, where cloud computing services have the most significant influence on quality followed by cost and responsiveness, respectively. However, cloud computing services do not significantly influence innovation and reliability.
