  This paper presents the results of an industry expert survey about event log
generation in process mining. It takes academic assumptions as a starting point
and elicits practitioner's assessments of statements about process execution,
process scoping, process discovery, and process analysis. The results of the
survey shed some light on challenges and perspectives around event log
generation, as well as on the relationship between process models and process
execution, and derive challenges for event log generation from it. The
responses indicate that particularly relevant challenges exist around data
integration and quality, and that process mining can benefit from a systematic
integration with more traditional and wide-spread business intelligence
approaches.
