B. Conformance Checking
   Conformance checking is the validation stage in the initial

process model generated against the event log data used. The
process model generated in the discovery stage can be sim-
plified by the Fuzzy Miner and Heuristic Miner algorithms to
avoid spaghetti processes through the simplification process.
The application of the Heuristic Miner in ProM is carried
out using an interactive Data-aware Heuristic Miner (iDHM),
while the application of the Fuzzy Miner is carried out using
Mine for a Fuzzy Model (Fig. 3).
