Activities starting with A_/O_/W_
Activities occurring in 80% of the traces
Completed traces only
Add artificial start events
Remove unnecessary transitions
Activities starting with either A_ or W_
Remove activities that follow another within seconds
Traces that executed an activity
Filter parallel activities
Remove outlier-long activities
Determine standard trace flow
Activities executed by resource X
Include life cycle transition
