Knowledge Management focuses on identifying, sharing, storing, and exploiting internal knowledge, whereas Open Innovation is more concerned with sources of external knowledge. However, this simple dichotomy between open and closed approaches is unhelpful and not realistic. Instead, it is the interaction between internal and external knowledge that creates dynamic capabilities and the ability to innovate. In particular, we need to better understand the interactions between internal and external knowledge, and how these influence innovation outcomes under different conditions. This edited volume, Managing Knowledge, Absorptive Capacity, and Innovation, provides an opportunity to combine contemporary interests in Open Innovation with the classic notion of absorptive capacity, to better understand how organisations can manage the absorption and exploitation of inbound external sources of knowledge in order to innovate.
