The body of knowledge in open innovation (OI) has been growing and, nowadays, it is one of the most popular and debated concepts in innovation management. However, the literature on OI is fragmented, many definitions have been used across the studies and in each paper different characteristics of open innovation are assessed. This issue creates many “flavors” of OI, which in turn creates obstacles for managers to implement open innovation practices. Also, this problem is an impediment for creating a unified body of knowledge. Thus, this paper addresses part of the problem by proposing a class of open innovation practices. This class encompasses all the OI “flavors” that answer the same question, “what should we innovate?”. Further, this class of OI practices is included in the current framework: inbound, outbound and coupled. This provides, in the product development context, a mindset that helps managers to be able to innovate more quickly, therefore the development of this classification can help companies to achieve competitive advantage.
