Currently, many old universities in Thailand have been facing the occurrence of lecturer massive retirement. This leads to the large amount of newly Ph. D. graduate recruitment for taking immediate responsibilities to teach and conduct research without mentoring by senior staff as well as in new universities. Therefore, this paper aims to propose the "Knowledge Management System Based Mentoring" which could be used to share and disseminate research experiences of the senior staff to enhance the abilities of newly Ph.D. graduate staff in the universities to supervise Ph.D. students to get the qualified research outputs. Knowledge engineering is employed to capture the effective mentoring practices particularly on Lateral Thinking in higher education. The Knowledge Management System had been implemented in department of Knowledge Management, The College of Arts, media and Technology, Chiang Mai University to mentor five newly Ph.D. graduate staff. The study explored the effectiveness of KMS in the case study of Ph.D. program in Knowledge Management is elicited from three senior professors (in social science, mathematics, as well as computer science and knowledge management) and modeled in CommonKADS. The Knowledge Management department is utilizing this mentoring knowledge for improving the research performance. The major output of the study is the effectiveness of "Knowledge Management System" KMS that helps to enhance abilities of newly Ph.D. graduate staff to supervise Ph.D. students productively.
