Percentage of cases in the event log that possess the same variant as any case in a group of cases.

Process with several possible execution variants.

Smaller coverage implies that the cases in a group of cases have been executed with higher flexibility than other cases in the event log.

Formula for practitioners

$\frac{ \sum_{c \in C} \begin{cases} 1 & \text{if } \exists tr \in \mathit{trace}(c) [tr \in \mathit{variants}(g)] \\ 0 & \text{otherwise} \end{cases} }{\mathit{count}(C)}$

$\mathit{trace}(c)$ returns the trace (sequence of activities) of case $c$.
$\mathit{variants}(g)$ returns the set of unique traces (variants) present in group $g$.
$\mathit{count}(C)$ returns the total number of cases in the event log.
