Enterprise IT Architecture Greenfield Design Combining IEC 62264 and TOGAF by Example of Battery Manufacturing

IT-systems supporting business operations are a cornerstone of industry 4.0 and smart manufacturing. IT-systems must not be considered as an end in itself. The enterprise IT architecture must be aligned with the business goals and strategy. Current approaches for designing enterprise IT architectures provide little guidance for greenfield environments in which there are little given boundaries, such as operation procedures. In smart manufacturing this is challenging due to the complexity of the shop floor involving OT and IT. This paper addresses this gap by combining the TOGAF architecture development method with the manufacturing operations management standard IEC 62264. The paper explores this combination by the example of designing an enterprise IT architecture for the Fraunhofer battery manufacturing research line involving the TOGAF phases architecture vision, business architecture, information systems architecture and technology architecture for manufacturing.
