This study is conducted within the domains of technology convergence and Open Innovation environment. Two frameworks have been adopted in the study, namely; Nexus of Forces and Capability-Based Framework for Open Innovation. The first purpose of the investigation was to identify to what extent and in what ways does Nexus of Forces affects the knowledge capabilities within the Open Innovation environment. The second purpose of the investigation was to identify what practical implications does Nexus of Forces brings to the Open Innovation practices. The investigation was conducted on a single company – Swisscom – by following a case study strategy. The methodological approach for collecting the data was a mixed method approach with concurrent embedded strategy. The study has focused mainly on qualitative data and the quantitative data was nested with the focus to strengthen the findings. For the primary data collection, 6 respondents were selected, Expert A and Expert B for interviews and 4 managers for survey.   In regard to the first purpose, our findings have shown that practices of Nexus of Forces have strategical implications on the process of managing knowledge capabilities. The extents of the NoF implications are through a direct and indirect level for the departments, which work with Open Innovation projects and at meta-level for the higher organizational structures within the company. In regard to the second purpose, our findings have shown that practices of Nexus of Forces have tactical implications on the Open Innovation practices. The final outcome of the study is a theoretical model that displays the strategical and tactical implications of Nexus of Forces on the knowledge capabilities and Open Innovation practices within the Open Innovation environment.
