The implementation was carried out by the software development department of SPIE AUTOMATION and in close coordination with the customer. Initially, a function-oriented prototype was developed that connected to the existing fault reporting system. Initial tests helped to collect performance indicators and optimize interface requirements. Subsequently, the software was further developed agilely in three sub-releases – with short feedback cycles and flexible adaptation to new customer requirements. On the way to the final solution, several challenges had to be overcome: The existing fault system first had to be examined and understood in detail. In addition, it was necessary to keep the delay time between the occurrence of a fault on the system and the live display or push notification to the responsible maintenance technician as short as possible. Furthermore, a flexible assignment of iPhones and system groups to individual persons had to be ensured in order to personalize fault messages precisely. The solution includes an iOS App for the maintenance technicians, which sends push notifications, enables photo documentation and offers direct feedback on fault processing. It is complemented by a web-based management platform for foremen and shift supervisors, which provides tools for shift planning, responsibility overview, attendance planning, fault statistics and history view. Technologically, the system is based on a modern stack of MQTT, MSSQL, React (Material-Design, Mobile-First), C#, Swift, SignalR, REST, OPCDA, LDAP as well as automated integration tests and CI/CD.
