Abstract
Open innovation has become a key strategic element to increase the generation and commercialization of innovations among big companies. Small and medium-sized firms (SMEs), that exhibit particular characteristics regarding organization, culture and strategy, have been more reluctant to adopt this approach. Thus little research exists on the adoption of open innovation among SMEs, and small and micro companies in particular. The paper presents the results of an explorative research design based upon semi-structured and narrative interviews that investigates particularities of small and micro firms regarding the sources of innovation, the strengths and weaknesses of their innovation process, and the potential of open innovation based on Web 2.0 technologies.
