Workplace learning has improved tremendously with the introduction of Internet online courses and networked information services. The internal communication within companies and the networking with a wide range of external information sources are crucial for the continuous increase of the organizational knowledge and continuous organizational learning. On the one hand organizational structures for building knowledge have to be lean enough to not restrain daily business; on the other hand these structures have to be easily adaptable to new vocational training needs. In the recent years, self-organized learning by means of personal learning environments has repeatedly been promoted as one possible solution to establish sustainable life-long learning mechanisms in dynamic and ever more technically dominated work environments. This master thesis investigates the opportunities and challenges that IT-supported learning and the integration of personal learning environments imply for learning and knowledge construction in small enterprises. At first, the characteristic structural features of small and medium enterprises in the creative industries, especially the software industries, are described and focus is laid upon these companies difficulties relating to the implementation of sustained professional trainings. Based on the investigations a concept is designed for the integration of personal learning environments into a company learning environment of a small and medium enterprise. By way of the case study it is explained how company learning environments help to face future challenges of work 4.0 by fostering information exchange and externalization of implicit knowledge within teams. In addition, it is argued that IT-supported, open and flexible, company learning environments may in the long term also support the harmonization of company procedures, learning aptitude, and especially, the whole staff competence development.
