For the daily operations management, an efficient use of all means of communication is an important cost and quality factor. MobiCall creates a complete network among machines, devices, sensors and the relevant staff members, thus allowing to directly transfer important process data, critical threshold values and faults. This process considers duty rosters as well as on-call schedules. As a consequence, workflows are optimised and, therefore, process costs are reduced, while the service quality is significantly improved. The MobiCall App plays a key role in this context. In fact, our app simplifies the cross-media planning, management, monitoring and implementation of tasks.
