Process mining fits in on the analytics side of the whole BI landscape (so, on the right side of the picture above). It has no particular methods to offer that help with the extraction or management of data. Since the consolidation of different data sources is also crucial for process mining in order to analyze endtoend processes, existing BI technology could be leveraged here. In my view ...
