Understanding how processes are executed is essential for all companies. While a certain amount of this knowledge can be explicated, a considerable amount is tacit, thus, it is in the mind of the employees. If this knowledge is not shared between organisational members knowledge loss/knowledge attrition is likely to occur. Especially SMEs have a high danger of knowledge loss as knowledge is concentrated on a limited number of individuals. To overcome this problem, we propose a risk-oriented knowledge map for SMEs. Based on the process architecture, risk of processes can be assessed. This allows identifying the knowledge risks associated with staff and thus providing the fundamental starting point for management to promote knowledge sharing as well as other knowledge management practices in the company to better cope with the danger of losing relevant knowledge.
