Over the last decades, digital transformation has profoundly reshaped production, broadening the scope and context of learning factories and creating the need for new approaches. To address the complexities of highly connected, flexible, and secure production, the concept of a Living Learning Company (LLC) is proposed. This concept extends the traditional learning factory beyond core production to encompass all relevant management, planning and support processes of a manufacturing company and their complex interrelations. Furthermore, it incorporates elements of living labs to ensure an innovative and user-centric learning environment and a sustainable business model for the LLC itself. The Open Industrial Training Center (OITC) at the Technical University of Applied Sciences Augsburg exemplifies this new concept, offering realistic, user-centric learning experiences for students, researchers, and industry professionals. The OITC’s multi-site infrastructure allows for interdisciplinary collaboration on topics such as efficient high-mix, low-volume manufacturing and assembly, IT/OT security and safety, and the integration of digital twins, collaborative robots, and IIoT in manufacturing processes. Additionally, it facilitates cross-enterprise networking and real-time integration of information systems on the scale of a mid-sized drone manufacturing company. As an LLC, the OITC acts as a platform blending inside-out and outside-in services to facilitate continuous exchange between academic education, research and industry needs. By addressing digitalization challenges in a realistic multi-site company setting, the OITC serves as a model for transforming learning factories to meet the demands of resilient, sustainable, and digitally transformed production.
