Mentoring is a powerful process that can help boost the knowledge transfer in an organization. However the traditional system of doing mentoring manually may resulted in unwanted constraints such as the time needed to schedule the mentoring sessions. This paper proposes an online mentoring system that provides a centralized knowledge sharing system for mentor and understudies or mentees. It allows mentoring sessions to happen at any time convenient to both parties. The system also provides mentoring among peers instead of just between mentor and understudies. © 2009 IEEE.
