Researchers view knowledge as an essential organizational asset for corporate success. Over the past decades, many studies explored the management of knowledge in multinational companies. Nowadays in the context of demographic change, intergenerational aspects and age have become crucial factors for knowledge sharing. However, it remains unclear how cultural attitudes affect knowledge sharing within companies. The purpose of this paper is to give new insights into the impact of culture and age on knowledge sharing in German and South-Korean companies. To understand how culture influences an individuals' perception of age and generation in the context of knowledge sharing in an organization, a qualitative approach including semi-structured interviews is chosen.
