—Online process mining techniques are increasingly
used to provide operational support. In this work we describe
tools to support distributed business processes which handle
sensitive data and require a high level of security together
with real-time validation. The techniques presented here have
been specifically developed for real-time compliance checking of
distributed processes in choreographies of heterogeneous entities.
Challenges include the fast aggregation, analysis and validation of
process logs that are collected from the distributed participants.
The autonomy of the participating entities has to be respected
and no sensitive data pertaining to the content of the individual
transactions must be accessed for process support and validation
purposes. A validation authority for process monitoring and
validation is set up. Together with software agents dispatched to
the participating entities the validation authority collects events
in a central log and then analyzes these events using a particular
representation of the process in form of a validation tree to
detect and resolve anomalies. We describe the application of
these technologies in a distributed business process with more
than 400,000 daily process executions. The business process is
supported by a help desk managing and responding to incidents
and anomalies. We observe a reduction of 90% of the calls to
the help desk and an average reduction of 15% in call length.
Further the help desk was enabled to act pro-actively, calling
participants to the process even before they became aware of
anomalies that affected their organization.
