Industry 4.0 (I4.0) is about creating an intelligent network of machines to handle increasing readjustment in the production system and increase productivity effectiveness. The requirements for the reconfigurability of production systems can be supported by an appropriate quality attribute scenario (QAS). This paper proposes a QAS for reconfigurability for I4.0 middleware software architectures. The expected benefit is a starting point to discuss and specify reconfigurable architectural requirements for production systems, e.g. between software architects and industry technology providers. Early results suggest that the QAS captures several relevant elements and therefore is a promising starting point to systematically specify reconfigurability QAS for I4.0 middleware software architectures.
