In the context of succession planning a huge number of critical knowledge can be at risk. This challenges smaller firms in particular. Based upon this, the chapter intends to highlight the contribution of IT-supported repositories to small and medium-sized enterprises (SME) succession planning as a promising approach to better cope with the risk of knowledge loss. More precisely, the aim of this chapter is to analyze different types of knowledge loss in the capture process with SME succession planning to demonstrate the potentials and deficiencies with IT-supported knowledge repositories. The findings presented in this chapter will hopefully contribute to a better understanding of how to deal with knowledge loss in the capture process when using IT-supported knowledge repositories for SME succession planning.
