Rework Count

\mathit{RewC}(g)

Dimension:

Cost

Granularity:

Group of cases

Number of times that any activity is instantiated again, after its first instantiation, in every case of a group of cases.

If the event log does not contain cost information, Rework Count can be used as a proxy for the cost performance of a group of cases.

Minimizing rework is desirable.

$\sum _{c \in g} \mathit{RewC}(c)$

$\mathit{RewC}(c)$ returns the rework count for case $c$ .

$\sum _{c \in g} \mathit{RewC}(c)$

This indicator is implemented in the process_performance_indicators Python library.
