$\frac{\mathit{RewC}(a)}{\mathit{I}(a)}$

$\mathit{RewC}(a)$ returns the rework count for activity $a$ .
$\mathit{I}(a)$ returns the total number of instances of activity $a$ .

$\frac{\mathit{RewC}(a)}{\mathit{I}(a)}$

This indicator is implemented in the process_performance_indicators Python library.
