This data is the foundation of all further activities and services. Basic operations concept 3 During the first two phases (engineering and manufacturing phases) CODIAG is set up in general for each class of system and subsequently for each individual system. ① In the initial project phase CV ME receives the customer’s requirement specification and starts the system selection and validation project ② Hardware engineers create a formal, structured representation of the requirements in XML format as „Configuration Specification“. This specification contains e.g. the required capacity or throughput requirement of the storage subsystem. ③ During manufacturing, in the final software installation and test phase the assembled system configuration is taken as „Factory Reference Snapshot“. This is the most detailed snapshot, 5 1.9.2013 Engineering Field Snapshot Configuration Specification Hospital Repair & 3.9.2013 Repair Snapshot Manufacturing Factory Snapshot containing also serial numbers of the system. The third phase is the continuous daily operation in the hospital and further phases deal with unexpected events. ④ In the hospital at the configured points in time, a snapshot is taken, similar to the Factory Reference Snapshot. Depending on the business unit, a comparison with previous runs and/or with the Configuation Specification or Factory Reference Snapshot can be done, but this is not mandatory. In any case, the resulting snapshot is prepared for transmission to the Siemens Headquarter and syngo Autoreport mechanisms take care of the transmission. ⑤ If an error occurs in the field and the system cannot be repaired locally, it is sent back to CV ME’s repair centers. The last Field Snapshot may be still on the system or already transferred to the HQ. ⑥ After arrival, a repair snapshot is taken. This snapshot can now be compared to the Configuration Specification, the Factory Reference Snapshot and the last Field Snapshot. These comparisons now enable a more detailed investiga- 7 Snapshot Deletion Recycling 6 6

After repair, the system can again be deployed in the field. ⑦ Eventually, if the system cannot be repaired, it will be recycled. All snapshots of this particular system will be removed from the databases, but of course the base Configuration Specification and snapshots of other systems still in the field are unaffected. Proactive Maintenance With the availability of consistent diagnostics data, further services can be offered by CV ME. The statistical analysis and trend analysis of data will be used to create predictions of components where a failure might be imminent. Proactively CS can be informed, that a service site visit should be scheduled or a replacement part could be dispatched to the responsible service technician or even the end customer, if so desired. Remote Diagnostics The latest hardware generations provide technologies that enable to remotely operate and diagnose a malfunctioning computer system. Of course this depends on the criticality of the error, e.g. if the power supply is broken, remote diagnostics cannot be used either. But in many cases skilled technicians can remotely reboot the system, run tests and perform error correction measures. Reduction of overall system failures A probability analysis showed, that in 48% of all computer failures – if remotely analyzed – a complete system exchange could possibly be avoided. The usage of Remote Diagnostics depends on a certain infrastructure on Healthcare’s and the customer’s site, so the deployment of this service is expected to more slowly ramp up over time, than the other services, Proactive Maintenance and Guided Local Diagnostics. Still, this service delivers the greatest benefits to CS and the customer. Guided Local Diagnostics Since the length of an on-site visit of a service technician is one of the largest cost drivers, CODIAG was designed, to performa a broad, but shallow depth analysis first in a very short time to detect a deviation from an expected configuration very efficiently. If combined with Remote Diagnostics or Proactive Maintenance to already identify a failed part time, the service technician can replace the spare part and then quickly test the repaired system, and check whether the configuration is valid. Proactive Maintenance Continuous system monitoring, transfer of data to Siemens HQ for analysis and predictions Increase part exchange, reduce system swap Guided Local Diagnostics Local analysis tools, tailored to Siemens systems and boards, requirement check and factory comparison Reduction of field service dispatch Reduction of on-site maintenance time Remote Diagnostics Remote network connect to system, diagnostics, repair or spare part dispatch, inform technician 7
