Expected sum of elapsed time between the start event of an activity instance and the complete event of the activity instance that precedes it, for all activity instances in a case belonging to a group of cases.

Event log in which the time spent between every activity instance is of relevance.

Minimizing waiting time is desirable.

Formula for practitioners

$\frac{\sum _{c \in g} \mathit{WT}(c)}{\mathit{C}(g)}$

$\mathit{WT}(c)$ returns the total waiting time of case $c$.
$\mathit{C}(g)$ returns the number of cases in group $g$.
