The paper describes an open online course which was run in 2015 under the title Corporate Learning 2.0. The course covered current developments, challenges, and trends in the field of corporate learning which evolve through the implementation of digital media. The course was designed in a way to support the collaborative and open generation of innovative ideas. The purpose of the study accompanying the course was to find out whether the target groups, mainly employees in companies in the field of corporate learning and human resource development, can be engaged in this type of online course and will exchange ideas openly in an online environment. The course was designed in a way that each week a new topic was introduced by the presentation of an actual and real challenge or problem in the field of corporate learning by one of the participating companies. Subsequently, the participants collected and exchanged ideas, got a deeper understanding of the problem and by doing so gained new insights into aspects of corporate learning. The design of the study included online questionnaires to access how participants evaluated the course, how they handled the technical platform which was used for communication processes and how they dealt with the openness of the course design. Additionally, tracking data was analysed as well as numbers of registration, badges, time for the completion of badges for each learning unit and so comparable data. The innovative aspect of the course lies in its approach to foster open innovation processes in the field of corporate learning, an area where this type of exchange has rarely been established yet (e.g. see Wallin and von Krogh, 2010; Chesbrough, 2006; Dahlander and Gann, 2010; Enkel and Gassmann, 2007). The course design is a prototype for an open online course in which a community of practice (Wenger, 1998) is used to exchange ideas and contribute solutions to real problems and challenges presented by companies. Therefore, the course served as an experiment to find out whether the target groups can be engaged in this kind of open exchange processes and whether it is possible to meet different interests such as personal learning for the individual learners as well as the generation of ideas for the participating companies.
