Dimension:

Quality

Granularity:

Group of cases

Description

Number of cases in a group of cases where a specific activity is the last one to be instantiated it.

Potential use

Formula for practitioners

$\displaystyle \sum_{c \in g} \begin{cases} 1 & \text{if } \exists i \in \mathit{endin}(c)[\mathit{act}(i) = \mathit{a}] \\ 0 & \text{otherwise} \end{cases}$

$\mathit{endin}(c)$ returns the set of last activity instances in case $c$ .
$\mathit{act}(i)$ returns the activity of activity instance $i$ .

Formal Definition

$|\{c \in g \mid \exists i \in \mathit{endin}(c)[\mathit{act}(i) = \mathit{a}]\}|$
