A Process Warehouse Model Capturing Process Variants.

Process Warehouses are a well-established means for analysing the execution of business processes and the computation of key performance indicators. We propose a new model for process warehouses which is better suited to cope with business processes which have many variants. We present a meta-model of processes with a notion of generic activities which then is used to automatically generate a generalisation hierarchy for process variants along which OLAP operations can be performed.
