Granularity:

Activity

Number of times that an activity is instantiated again, after it is instantiated a certain number of times, in any case of the event log.

Process where rework recurrently occurs.

Minimizing rework is desirable.

$\sum _{c \in C} \mathit{max}(0, \mathit{count}(c, a) - \mathit{val})$

$\mathit{count}(c, a)$ returns the number of instances of activity $a$ in case $c$ .

$\sum _{c \in C} \mathit{max}(0, \mathit{count}(c, a) - \mathit{val})$

This indicator is implemented in the process_performance_indicators Python library.
